AIRPAX / SENSATA AP12172203 Magnetic Circuit Protector

The Airpax AP series hydraulic magnetic circuit protectors offer a robust solution for power switching and circuit protection. Unlike thermal protectors, the AP maintains a consistent trip current across a wide temperature range. Available in DC, 50/60Hz, or 400Hz versions with adjustable delays, these protectors are suitable for communication, navigation, aircraft instrumentation, radar, and power supplies. The 'trip-free' action ensures the circuit opens even when the handle is held in the ON position. The AP series is also available as the UP series, recognized by UL and CSA, and the AP-MIL series, manufactured to MIL-PRF-39019 standards. Multi-pole configurations allow for protection of multiple circuits with various coil combinations.
