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.
