FAZ-NA circuit breakers **PRODUCT OVERVIEW** 

## UL 489 DIN rail branch circuit breakers 

## **Tripping curves to choose from** 

Eaton FAZ-NA branch circuit breakers are available with “B,” “C” and “D” tripping characteristics. B-curve devices are suitable for applications where low levels of inrush current are expected. 

C-curve devices are suitable for applications where medium levels of inrush current are expected. Applications include small transformers, lighting, pilot devices, control circuits and coils. C-curve devices provide a medium magnetic trip point. 

D-curve devices are suitable for applications where high levels of inrush current are expected. The high magnetic trip point prevents nuisance tripping in high inductive applications such as motors, transformers and power supplies. 

Eaton FAZ-NA devices are current limiting, which means they interrupt fault currents within one half cycle of the fault. Current limiting devices offer superior protection by reducing peak let-through current and energy. 

## **Device printing on front and side** 

## Installation options 

These branch circuit breakers are available in two terminal configurations: standard box terminals that accept multiple conductors and ring-tongue terminals, ideally suited to demanding requirements of the semi-conductor industry. All breakers mount on standard 35 mm DIN rail. Bus connectors and feeder terminal facilitate mounting and wiring of multiple miniature circuit breaker arrays in control panel assemblies. These circuit breakers can also be reverse feed.

## UL 489 DIN rail branch circuit breakers 

## FAZ-NA circuit breakers 

## **ACCESSORIES** 

## **Tripping signal switch Z-NHK, Z-IHK-NA** 

- Design according to IEC/EN 60947-5-1, IEC/EN 62019 

- Field installable 

- The specified minimum voltages are per contact—take into account particularly in case of series connection 

- Self-cleaning contacts 

- Contact material and design particularly suitable for extra low voltage 

- Z-NHK: the function of one of the two change-over contacts can be switched from “auxiliary switch” to “tripping signal switch” 

- Tripping signal contact transmits message of electric tripping, not mechanical switch-off 

- Test key for contact function “electrical tripping” 

- Z-IHK-NA: will allow for > 480Y/277 Vac rating

## **Six tripping curves to choose from** 

Eaton FAZ supplementary protectors are available with six different tripping characteristics, including Type B, C, D, K, S, and Z. Definitions for each trip curve are contained on the ordering pages and can be used to determine the optimal characteristic for your application. For example, low-level short-circuit faults in control wiring, such as PLCs, are best protected by devices with Type B trip characteristics (3–5X continuous rating of the device ( _I_ n). 

Even though not required by NEC or CEC for supplementary protectors, Eaton’s FAZ devices are current limiting, which means that they interrupt fault currents within one half cycle. Current limiting devices offer superior protection by reducing peak let-through current and energy.

## **Applying branch circuit breakers and supplementary protectors in North America** 

## **Characteristics of IEC-style miniature circuit breakers** 

Because FAZ miniature circuit breakers are IEC-style devices, it is important to understand their inherent characteristics before examining them in the context of UL/CSA requirements. 

- IEC-style miniature circuit breakers are thermal-magnetic, inverse time protective devices, with both a fixed thermal and a fixed magnetic trip setting 

- They are toggle operated, and like all modern circuit breakers, feature a “trip-free” mechanism; this means that the tripping action works independently of the handle position for safety purposes 

- They all mount on a standard 35 mm DIN rail and share a common single pole width of 17.5 mm 

- Most comply with EN/IEC 60898 and EN/IEC 60947-2, which are the relevant international performance and testing standards for low voltage (<1000V) circuit breakers in Europe and the rest of the IEC world 

- Outside North America, they can be used in both residential and industrial applications as feeder and branch circuit protective devices 

The Eaton series offer two types of miniature circuit breakers for use in North America. The first version, FAZ-NA(RT), fully complies with the molded-case circuit breaker standard UL 489 and the Canadian equivalent CSA 22.2 No. 5-09, which states that devices within that range can be applied legitimately as feeder and branch circuit protective devices per the U.S. and Canadian electrical codes. 

A second version, FAZ, is recognized per UL 1077 and certified per CSA C22.2 No. 235 as a supplementary protector and can be fully used per the NEC and CEC Codes in that capacity. For international purposes, the entire FAZ family is CE marked and in full conformity with the applicable IEC standards for miniature circuit breakers, EN/IEC 60898 and EN/IEC 60947-2. 

- In North America, most European miniature circuit breakers are only UL recognized and CSA certified as “supplementary protectors,” meaning that they cannot be utilized as feeder or branch circuit protective devices per the local electrical codes. This commonly restricts their use to applications where “closer” protection is desired than that offered by a branch circuit protection device 

- Some variations, like the FAZ-NA(RT) line have been specially designed to meet UL and CSA requirements for molded-case circuit breakers and are marked accordingly. This makes them suitable for feeder and branch circuit protection applications in North America 

Both FAZ and FAZ-NA(RT) are offered in various ampere ranges and tripping characteristics. This paper will focus on the main technical aspects of the entire line and should assist in the proper selection and application of all versions.

## Miniature circuit breaker application 

## FAZ circuit breakers 

## **PRODUCT OVERVIEW** 

## **Supplementary protectors** 

As mentioned, the standard FAZ line fulfills all of the criteria per code of “supplementary overcurrent protective devices,” or “supplementary protectors,” as they are better known. 

## **What is the definition of a supplementary protector per North American standards?** 

A supplementary protector is a manual reset device designed to open the circuit automatically on a predetermined value of time versus current or voltage within an appliance or other electrical equipment. It may also be provided with manual means for opening or closing the circuit. (Source: UL 1077) 

In the United States (and similarly in Canada) the NEC 2005 further defines supplementary protectors as devices intended to provide limited overcurrent protection for specific applications, such as lighting fixtures and appliances. This limited protection is in addition to the protection provided in the required branch circuit by the branch circuit overcurrent protective device. 

Clearly, the underlying message in those definitions is that supplementary protectors are not branch circuit overcurrent protective devices per code, and neither are they tested that way per UL and CSA standards. They cannot replace the primary protective role performed by listed and certified molded case circuit breakers and fuses. 

That explains, in part, their status by UL as “recognized only” devices. Supplementary protectors will never bear a UL listing mark, simply because their suitability as protective devices is dependent on a number of acceptability conditions that can vary from make to make and ultimately define the manner in which they can be properly applied per code. The manufacturer should be consulted in all cases when evaluating the suitability of “recognized only” components such as UL 1077 supplementary protectors. 

FAZ protectors are not subject to any specific restrictions in this respect, other than, like all supplementary protectors, they must never be used as a substitute for true listed and certified primary overcurrent protective devices. 

## **Where can supplementary protectors be used effectively per code standards?** 

Eaton series FAZ supplementary protectors can be used in a number of significant areas. To more clearly illustrate potential applications, however, let’s first present the NEC’s definition of a branch circuit: 

## **The circuit conductors between the final overcurrent device protecting the circuit and the outlets. (Sourcee: NEC)** 

A branch circuit is that portion of the electrical distribution system that extends beyond the final branch circuit overcurrent protective device and is intended to serve lighting, appliance, motors, and/or other individual loads. 

Typically, the branch circuit overcurrent protective device (BOPD) will be either a listed molded-case circuit breaker or a fuse. Supplementary protectors, such as FAZ devices from the Eaton series, can therefore be added to any of these branch circuits to “supplement” the branch circuit protection. Examples of applications ideally suited for these devices can include: 

- Any type of OEM electrical equipment that is fed from a service panel board and that often requires additional protection for sensitive internal circuitry and components (test and medical equipment, copiers and printers, computers and power supplies, etc.) 

- The need for manual reset devices with optional accessories such as auxiliary contacts and voltage trips to accomplish fuseless protective circuit designs and enhance operational diagnostics 

- Isolation and protection of control cable, coils, contacts, and circuit elements of motor control circuits tapped from the load side of the branch circuit protective device (per NEC 430.72) 

- Protection of control circuit transformers, especially in the secondary where the manual reset protector can be used to isolate, as well as protect, secondary circuit conductors and loads 

IEC-based miniature circuit breakers, such as the entire FAZ line, are much more than just conventional supplementary protectors from an internal design point of view and can provide an ideal means to enhance the protective capabilities of any circuit. 

- As mentioned, they are in full compliance with the pertinent EN/IEC standards (EN/IEC 60898, EN/IEC 60947-2) for miniature circuit breakers and can thus be applied, outside of North America, as full-fledged stand-alone overcurrent protective devices in both residential and industrial applications 

- As this typical let-through current curve shows, they are highly current limiting devices that appreciably limit the amount of let-through current and destructive energy within their ratings to minimize damage levels to downstream loads and circuits 

Circuit breakers that are classified as “current limiting” have the ability to clear damaging short-circuit currents within the first half-cycle of the fault, resulting in better overall protection for all circuit components. 

- They come in a variety of tripping characteristics, which is ideal when customizing protection to match specific load requirements. FAZ supplementary protectors offer a total of six different protection characteristics for this purpose: B, C, D, K, S, and Z tripping characteristics 

- They feature a number of electrical accessories to enhance the performance and diagnostic capabilities of control panels, as well as a means to facilitate panel mounting and wiring

## Miniature circuit breaker application 

## FAZ circuit breakers **PRODUCT OVERVIEW** 

## **Typical let-through curve profile of a current-limiting device** 

- The X axis shows the prospective short-circuit current levels 

- The Y axis indicates the actual let-through values (let-through current in the example shown) at those prospective fault ratings for each FAZ device plotted 

As can be interpreted from the bend in the plotted curves, each device acts to limit the damaging let-through energy (and current) at those values of short-circuit current. 

By design, all Eaton series FAZ supplementary protectors and miniature molded-case circuit breakers are current-limiting protective devices.

The following magnetic response times apply to each of the characteristic letters referenced in Eaton series FAZ part numbers: 

- B: Instantaneous response of 3–5x Irating of each unit)—ideally suited for resistive loads,  n (In = fixed current such as conductors or heaters 

- C: Instantaneous response of 5–10x Ifor inductive loads, such as motors and solenoidsn—ideally suited 

- D: Instantaneous response of 10–20x Ifor highly inductive loads, such as lighting and higher  n—ideally suited efficiency motors 

- K: Instantaneous response of 8–12x In—ideally suited for highly inductive loads, similar to D but with a narrower range 

- S: Instantaneous response of 13–17x Ifor highly inductive loads, especially in control circuits  n—ideally suited with coils and light filaments 

- Z: Instantaneous response of 2–3x Isetting to provide tighter protection for loads that are more  n—very low instantaneous sensitive to the effects of overcurrents 

## **Typical “inverse time” tripping characteristic of a miniature circuit breaker** 

- “Inverse time” refers to the device’s tripping characteristic; as the curve shows, the higher the current, the lower the tripping time 

- The trip response on the thermal portion is uniform throughout the line 

- The instantaneous response differs, depending on the characteristic selected. (i.e., B, C, or D) 

- Tripping is very quick (less than a half-cycle) in the upper range of overcurrents (bottom right) due to the current-limiting design of the Eaton series miniature circuit breakers 

## **Tripping characteristics** 

Miniature circuit breakers are thermal-magnetic, inverse-time tripping devices. From a thermal point of view, all FAZ protectors are calibrated to trip at the same level, which is 135% of the device’s fixed current rating for single-pole and 145% for multi-pole at an ambient reference temperature of 40°C. 

**Notee:** Higher ambient temperatures, as well as density of mounting groups, can all be accommodated but may be subject to de-rating factors. Please consult technical data for further information and appropriate curves. 

It is the response time of the magnetic trip that differentiates each characteristic and for which an identifying letter is assigned. The IEC 898 standard only specifically covers the B, C, and D characteristics. The rest can vary from brand to brand, but essentially follow a uniform convention.

## **FAZ-NA(RT) miniature circuit breakers** 

As previously mentioned, we have expanded our FAZ line of miniature circuit breakers to include a version that is listed and certified as a molded-case circuit breaker (UL 489 and CSA No. 5). 

This line is rated up to 40A and comes in single-, two-, and three-pole versions with instantaneous trip characteristics B, C and D. Of course, the line is also in conformity with the IEC standard for molded-case circuit breakers, IEC 60947-2, and can therefore be universally applied. 

The NEC defines a circuit breaker as follows: 

## **A device designed to open and close a circuit by nonautomatic means and to open the circuit automatically on a predetermined overcurrent** _**without damage to itself when properly applied within its rating.**_ 

Note the text in italics. In the eyes of the code, that definition sets circuit breakers apart from any other protective device and establishes their role as primary overcurrent protective switches in all types of electrical circuits. UL listing (and CSA Certification) requires additionally that regular testing on circuit breakers be conducted by UL and CSA at the manufacturer’s plant to monitor construction and verify their performance. 

The Eaton series new miniature molded-case circuit breaker line includes two types: the FAZ-NA with traditional box terminals for multiple wires, and the FAZ-RT which accommodates ring-tongue terminals.

As already mentioned, all Eaton series FAZ devices are current-limiting by design. In the case of the UL 489 devices, they are also classified by UL/CSA in that manner and are marked on the label. 

A circuit breaker that is marked as a current-limiting device is one that does not use a fusible element and, when operating within its current-limiting range, limits the let-through energy (I[2] t) to less than the energy of a half-cycle wave of the available symmetrical current. 

The label on FAZ-NA(RT) devices lists the actual let-through energy (I[2] t = 60 kA2 s) and peak let-through current (6.2 kA) at the maximum interrupting rating of 10 kA. 

Current-limiting circuit breakers substantially reduce the amount of damage sustained by downstream components in the event of a high short-circuit fault by clearing the fault in the shortest amount of time possible due to the quick separation of its contacts and ensuing extinction of the arc current. 

## **HACR and SWD** 

FAZ-NA(RT) circuit breakers are also marked “HACR” for use in heating, air conditioning, and refrigeration applications. In addition, the abbreviation “SWD” on the label indicates that the devices are suitable for switching fluorescent lighting loads on a regular basis.

## **Short-circuit markings on FAZ devices** 

Below is a tabulated summary of short-circuit rating values that apply to the FAZ line of supplementary protectors and moldedcase circuit breakers. 

It is important to keep in mind that short-circuit markings on FAZ supplementary protectors (UL 1077) and FAZ-NA(RT) molded-case circuit breakers (UL 489) must not be interpreted in the same manner. 

Supplementary protectors have short-circuit markings in association with upstream primary overcurrent protective devices. Conversely, molded-case circuit breakers are primary overcurrent protective devices, and their ratings thus refer to their short-circuit interrupting capability.

a A circuit breaker with a 480Y/277 Vac rating can be applied in a solidly grounded circuit where the nominal voltage of any conductor to ground does not exceed the lower value of the circuit breaker’s rating (e.g., 277 Vac) and the nominal voltage between any two conductors does not exceed its higher value (480 Vac). These ratings typically can be found on protective devices such as molded-case circuit breakers and self-protected “Type E” combination motor controllers.
