The AP12-1-71-102 is a two-pole, series trip magnetic circuit protector designed for reliable overcurrent protection and power switching. It features a nominal current rating of 1.0A and is versatile enough to operate on DC, 50/60Hz, and 400Hz power systems. This model incorporates a short time delay with a 135% trip characteristic, and its hydraulic-magnetic mechanism ensures the trip current is unaffected by wide temperature variations. As part of the fully sealed AP series, it provides a trip-free action to prevent being held closed during an overload and uses a bushing mount with two 6-32 threaded inserts. Typical applications include communication equipment, navigation systems, aircraft instrumentation, radar, and power supplies.
