The AP17-1-64-102 is a two-pole, fully sealed magnetic circuit protector designed for reliable overcurrent protection and power switching. This model features a series trip configuration with screw terminals, a nominal current rating of 1.0A, and is intended for 50/60Hz systems. It incorporates a high-pulse, short time delay (delay code 64) that provides excellent tolerance for inrush currents without nuisance tripping. As a hydraulic-magnetic protector, its performance is stable across a wide temperature range, and its trip-free mechanism ensures safety by opening the circuit during an overload even if the handle is held on. Typical applications include communication systems, navigation equipment, aircraft instrumentation, and power supplies.
