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 22.2- No. 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.

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.

Trip Indication

The operating handle moves positively to the OFF position.

Ambient Operation

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

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.

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.

Poles

One through three poles available.
