The AP17-1-62-752 is a two-pole, series-trip magnetic circuit protector that combines power switching with reliable overcurrent protection. It is designed for 50/60Hz applications with a nominal current rating of 7.5A and features a long time delay characteristic. As a hydraulic-magnetic protector, its trip current is stable over a wide temperature range from -40°C to +100°C, and its trip-free mechanism ensures the circuit opens during an overload even if the handle is held ON. This model uses screw terminals and is mounted via a 3/8" threaded bushing and two 6-32 threaded inserts, making it suitable for applications like power supplies, communication equipment, and aircraft instrumentation.
