## AIRPAX: **IPA/CPA Series** | Hydraulic Magnetic Circuit Protectors 

## **INTRODUCTION** 

The Airpax™ IPA/CPA hydraulic-magnetic circuit protectors provide low-cost power switching, reliable circuit protection and accurate circuit control for equipment in the international marketplace. 

IPA models meet IEC spacing requirements that are mandatory for equipment which must comply with IEC specifications 601 and 950 and VDE specifications 0804 and 0805. In addition, they are UL Recognized as supplementary protectors per UL STD. 1077, CSA Certified as supplementary protectors per CSA C 22.2No. 235, TUV Approved to VDE 0642 (EN60934), CCC Approved (pending) and CE Compliant. 

Designed using the latest in sensitive hydraulic magnetic technology, the IPA line adapts itself to many applications and environments. They’re ideal for data processing and business 

machines, medical instrumentation, broadcast equipment, vending and amusement machines, military applications and wherever precision operation is required. Temperature differences which affect fuses and other thermal devices are not a concern. 

One important feature of this protector line is a “trip free” action, which means the circuit will trip in the presence of an overload even though the handle is held in the ON position. The delay mechanism senses the fault and the contacts open. 

The IPA is available in configurations including series and series with auxiliary switch, with a choice of delays and ratings in either DC, 50/60Hz or 400Hz versions. Single or multi-pole versions are available, with a variety of pole arrangements to meet your specifications.

## **MULTI-POLE CIRCUIT PROTECTORS** 

## **Two Pole Protectors** 

An assembly consisting of two single pole units, having their trip mechanisms internally coupled and with a single toggle handle, forms the IPA-11 with quick-connect D.I.N.-style terminals. Individual poles may differ in ratings, delays and internal connections. An auxiliary switch may be included in either or both poles, allowing you to mix SELV and hazardous voltages. Rugged screw-type terminals can be provided, in which case the designation would be IPA-66. The IPAH offers a toggle handle for each pole. 

## **Three Pole Protectors** 

The three pole construction consists of three single pole units assembled with an internal mechanical interlock which actuates 

all units simultaneously. A single toggle handle operates all three poles for quick and convenient control, or if preferred, a handle per pole is available. The individual poles need not have identical characteristics and any series trip pole may have an auxiliary switch. If screw-type terminals are required, the breaker designation will be IPA-666 for a three pole version. 

Breaker poles are numbered consecutively when viewed from the terminal side, with the ON position up, starting with Pole #1 on the left side and proceeding to the right. 

## **Handles** 

The IPAH two and three pole models are available with a handle per pole.

## **CONFIGURATIONS** 

## **Series Trip** 

The most popular configuration for magnetic protectors is the series trip where the sensing coil and contacts are in series with the load being protected. In addition to providing conventional overcurrent protection, the handle position conveniently indicates circuit status. 

## **Auxiliary Switch (Applies to Series Trip Only)** 

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 contacts actuate simultaneously with the main breaker contacts, and will open regardless of whether the breaker contacts are opened manually or electrically. For auxiliary switch ratings below 6Vac or 5Vdc, an auxiliary switch with gold contacts, designated as REG, is available. Gold contacts are not recommended for load current above 100 milliamps. An optional auxiliary switch, RS, configuration allows an alarm or signal to be forwarded only upon electrical overload, allowing for easier detection of fault circuit.

## **DC Delay Curves (typ)** 

## **DELAY CURVES - DC, 50/60HZ, 400HZ** 

A choice of delays is offered for DC, 50/60Hz and 400Hz applications. 

Delays 40, 59 and 69 provide fast acting, instantaneous trip and are often used to protect sensitive electronic equipment (not recommended where a known inrush exists). 

Delays 41, 51 and 61 have a short delay for general purpose applications. 

Delays 42, 52 and 62 are long enough to start certain types of motors and most transformer and capacitor loads. 

Delays 400, 500 and 600 are long delays for special motor applications.

## **SPECIFICATIONS** 

## **Trip Free** 

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

## **Construction** 

Series and series with auxiliary switch available in various delays and combinations. 

## **Auxiliary and Alarm Switch** 

## **Trip Indication** 

The operating handle moves positively to the OFF position. 

When supplied shall be S.P.D.T. configuration with a maximum rating of 3.0 amperes, 250Vac resistive load. Gold contacts are rated at .100 amperes, 125Vac resistive load. 

## **Ambient Operation** 

IPA protectors operate in temperatures between –40°C and +85°C. 

## **Moisture Resistance** 

Meet all the requirements of MIL-PRF-55629 when tested in accordance with Method 106 of MIL-STD-202. 

## **Insulation Resistance** 

Not less than 100 megohms at 500 volts DC. 

## **Dielectric Strength** 

IPA protectors withstand 3000Vac, 60Hz for 60 seconds between all electrically isolated terminals except auxiliary switch terminals shall withstand 500Vac, 60Hz for REG and REC types. 

## **Endurance** 

Operating as a switch, the operating life exceeds 10,000 operations, at rated current, at a rate of 6 per minute. 

## **Salt Spray (Corrosion)** 

Meet the requirements of MIL-PRF-55629 when tested in accordance with Method 101 of MIL-STD-202. 

## **Shock** 

Circuit protectors shall not trip when tested per MIL-STD-202, Method 213, Test Condition B with 100% rated current applied to delayed units and 80% rated current to instantaneous units. Units with auxiliary switches will withstand 30G max. 

## **Vibration** 

## **Electrical Characteristics** 

IPA protectors are rated .050 to 30 amperes 65Vdc; .050 to 30 amperes 240 Vac 50/60Hz; 0.050 to 15 amperes 250Vac, 400Hz. 

Circuit protectors shall not trip when vibrated per MIL-STD-202, Method 201, Test Condition A with 100% rated current applied to delayed units and 80% rated current to instantaneous units. 

## **Poles** 

One through three poles available.

Note: 

> A  The coding given permits a self-assigning part number.  Other configurations may require a factory assigned part number. Typical examples are units with mixed ratings, combinations of styles or construction. With these, it is suggested that order entry be by description and/or drawings and a part number will be assigned. Additionally, it is a standard policy to establish a factory assigned part number wherever a descriptive drawing exits to provide cross reference, traceability and manufacturing control.

**3** Third Decision Configurations **-0** Switch only **-1** Series **-1REC4** Series with silver contact Auxiliary switch **-1REG4** Series with gold contact Auxiliary switch **-1RS4** Series with silver contact Alarm switch **-1RSG4** Series with gold contact Alarm switch Notes: 1. For switch type, eliminate 4th & 5th decision. 2. Switch will be marked with Max. current & voltage. 3. The alarm switch is located in the handle pole for single handle types and in pole 2 for units with a handle per pole. The  auxilliary switch may be located in any pole. However the standard location is in pole 2. 4. Switch type with alarm switch must be multi-pole connected to a pole equipped with either an overcurrent or overvoltage mechanism. (Consult factory for further information.)
