AIRPAX: | **T/R/PP/PR CR/CPP/CPR Series** Hydraulic Magnetic Circuit Protectors (SNAPAK®) 

## **INTRODUCTION** 

The Airpax™ SNAPAK® series is a snap-acting hydraulicmagnetic circuit protector that combines power switching and accurate, reliable circuit protection in one aesthetically pleasing package.  The SNAPAK® combines the functions of three separate components: power switch, fuse and fuse holder. To the OEM, this means that only one item has to be mounted instead of three. Less assembly is required, inventory is cut by twothirds and greater panel density is obtainable with less clutter. In addition, the SNAPAK® can be operated at either DC or 50/60Hz, eliminating the need to specify, order and stock separate units. 400Hz units are also available. 

To enhance front-panel aesthetics, SNAPAK® is offered with paddle and rocker handles in six attractive colors and push-pull and push-to-reset actuators. Also offered is a variety of optional mounting hardware. The push-pull version is supplied with a black button with a white indicating band. 

SNAPAK® circuit protectors are UL Recognized as supplementary protectors per UL STD. 1077, CSA Certified as supplementary protectors per CSA STD. C22.2 No. 235, VDE Approved as circuit breakers for equipment per STD. EN 60934, CCC Approved and CE Compliant. In addition, most versions are certified by UL to meet spacing requirements of IEC 950 for basic and functional insulation for front panel mounting. 

Consult factory for details and exceptions. Typical applications include office appliances, electronic data processing, medical equipment, business machines, vending and amusement machines. Push-pull versions are particularly well suited for medical instrumentation, automotive production transfer lines and other applications where accidental turn off is unacceptable. For those applications which do not require circuit protection, SNAPAK® is offered in a power-switch-only configuration. 

Orientation of the button when marked with an amperage notation must be specified when using the fourth decision table. Push-to-reset is supplied with a contrasting color indicating shaft. In addition, SNAPAK® is offered in SPST and DPST configurations. The sin-gle pole satisfies most applications. The two-pole version is often used for extra safety in products that utilize high voltage or where current sensing and breaking of both sides of the line is required. 

Since the SNAPAK® is snap-acting, it assures immediate opening and closing of the contacts. Its design also prevents operator “teasing” of the contacts and minimizes arcing.

## **Series Trip** 

The most popular configuration for magnetic protectors is the series trip where the sensing coil and the contacts are in series with the load being protected. In addition to providing conventional overcurrent protection, it is simultaneously used as an on-off switch.

Shunt Trip Single Pole Two Pole ( 1 pole shunt) 

## **Shunt Trip** 

The shunt trip is designed for controlling two separate loads with one assembly. The control is established by providing overload protection for the critical load. when the current through this load becomes excessive and reaches the trip point, the protector will open and remove power from both loads simultaneously. The current rating of both loads must not exceed the maximum contact rating.

Relay Trip (Note A) Single Pole Two Pole (1 pole relay) 

## **Relay Trip** 

This permits the overload sensing coil to be placed in a circuit which is electrically isolated from the contacts. The coil may be actuated by sensors monitoring pressure, flow, temperature, speed, etc. Other typical applications include crowbar, interlock and emergency/rapid shutdown circuitry. Trip may be accomplished by voltage or current, which must be removed after trip.

## **Auxiliary Switch** 

This is furnished as an integral part of a series pole in single or, multi-pole assemblies. Isolated electrically from the protector s circuit, the switch works in unison with the power contacts and provides indication at a remote location of the protector’s ON-OFF status.

Auxiliary Switch (Note B) Two Pole 

## **Voltage Trip** 

Sometimes called “dump circuits” or “panic trip circuits,” these units make it possible to open main power contacts with lower power inputs from one or more sources. This configuration is becoming increasingly more important for sensitive circuitry and denser packaging in automation systems. Available in series, shunt or relay configurations.

Note B:  Switch is located in the left hand pole (viewed from terminal end). 

## **Power Switch** 

In the event that over-current protection is not desired, the coil mechanism can be deleted, providing an excellent low cost single or double-pole power switch. Maximum current rating is 15 amps.

## OPERATING CHARACTERISTICS 

## **MAxIMUM DCR AND IMPeDANCe** 

## **Inrush Pulse Tolerance** 

Many circuit protector applications involve a transformer turn-on, an incandescent lamp load, or a capacitor charge from a DC source. Each of these applications has one common factor: a steep transient of very high current amplitude and short duration. This takes the form of a spike or a single pulse and is the cause of most nuisance tripping associated with magnetic circuit breakers. 

SNAPAK[®] will withstand, without tripping, a single pulse of 8 milli-seconds duration (half sine wave configuration) and peak amplitude of 9 times its rating without the inertia wheel and 13 times its rating with an inertia wheel. (Not applicable to instant trip delays).

## DELAy CURVES & SPECIFICATIONS 

## **400 Hz, DC, 50/60Hz Delay Curves (typ)** 

A choice of delays is offered for DC, 50/60Hz and 400Hz applications. Delays 0, 49, 59 and 69 provide fast-acting, instantaneous trip and are often used to protect sensitive electronic equipment (not recommended where known inrush exists). Delays 1, 41, 51 and 61 have a short delay for general purpose applications. Delays 2, 42, 52 and 62 are long enough to start certain types of motors and most transformer and capacitor loads. 

## **Trip Free** 

will trip open on overload, even when forcibly held on.This prevents operator from damaging the circuit by holding handle in the ON position. 

## **Trip Indication** 

The operating handle moves forcibly and positively to the OFF position on overload. 

## **Ambient Operation** 

Operates normally in temperatures between –40° C and +85°C. 

## **Insulation Resistance** 

Not less than 100 megohms at 500Vdc. 

## **Dielectric Strength** 

withstands 1500 volts, 60Hz for 60 seconds or 1800Vac for one second between all electrically isolated terminals. 

## **endurance** 

Mechanical life in excess of 50,000 operations. In many applications, however, contact wear due to the electrical load determines unit life. At maximum electrical ratings, the SNAPAK[®] can perform 10,000 operations at rated current and voltage. Under UL 1077, the SNAPAK[®] can perform 50 operations at 150% of maximum rated current followed by 6,000 operations at maximum rated current. Under VDE 0642 (EN60934) the SNAPAK[®] can perform 6,000 electrical operations. After any endurance cycle, the breaker will calibrate and have working dielectric strength.

## HOw TO ORDER 

The ordering code for the SNAPAK[®] circuit protectors may be determined by following the steps in the decision tables shown here. 

The coding given permits a self-assigning part number, with certain limitations (due to the adaptability of magnetic protectors to complex circuits), requires a factoryassigned part number. 

The example shown is the code for a paddle handle, single pole (UL construction), series circuit protector designed for operation of a 50/60Hz/DC circuit. A slow time delay and rating of 5 amperes has been indicated. Handle color is black, and a bright nickel knurled nut, vertical mount (ON-OFF) indicator plate and locking ring are to be supplied. 

To determine the ordering code for your particular SNAPAK[®] unit, simply follow the steps shown, then fill in the letters and/or numbers in the boxes. Space is available on the circuit breaker label for your part number (up to 12 digits). you may then use your own part number to place an order or as a reference for further questions you may have. This option does require a factory assigned part number for traceability to your drawing or internal part number.

Notes: 

- A  A neon bulb is provided when specified for 120Vac and 250Vac operation. For operation at 120Vac a 33,000 ohm, 1/2 watt external resistor is required. At 250Vac a 100,000 ohm, 1 watt external resistor is required. 

- B    An LED with 750 ft. L @ 20mA is provided in the center of the handle. Maximum power dissipation @ 25°C is 135mW. Continuous forward current is 20mA. Forward voltage, typical, is 1.6v at 20mA. Reverse current, typical, is 100mA @ 3.0 volts. An external resistor may be required to limit current to these values. 

- C  When ordering Paddle Handles, you may choose one item from each hardware group to add to 5th decision if such items are desired. For example, “-11ALS” would indicate a bright nickel knurled nut, plus a vertical mount indicator, plus a locking ring, plus #6-32 screw terminal adapters. For Push-Pull, Rocker and Push-to-Reset versions, you may add only the #6-32 screw terminal adapters (-S). 

- D  All units except Rocker units will have (1) hex nut installed as standard hardware for the back of a panel. The choices in the fifth decision table are intended for the front or visible side of the panel and are offered for Paddle Handle configuration only. Push-Pull and Push-to-Reset configurations include one (1) panel nut and one (1) hex nut as standard hardware. 

- E Switch only — no current overload protection provided.

This approval requires the addition of a C at the end of the part number. The unit will not be VDE approved. 

The shaded areas denote VDE approval, CCC approval (if applicable) and CE compliant options. This approval requires the addition of a V at the end of the part number. The V will be added to any part number formed entirely from shaded decisions. If non-shaded areas are selected, the unit will not be VDE approved, nor CE compliant, but other approvals still apply.
