AIRPAX / SENSATA AP12165F203 Magnetic Circuit Protector

The Airpax™ AP series are fully sealed, magnetic circuit protectors combining power switching and accurate, reliable circuit protection with inverse time delays and trip-free features. Unlike thermal protectors, the AP maintains a consistent trip current across a wide temperature range. Available in DC, 50/60Hz, or 400Hz versions with various delays, they cater to specific application requirements. The 'trip-free' action ensures the circuit remains open even if the handle is held in the ON position. These protectors are suitable for communication, navigation, aircraft instrumentation, radar, and power supplies. The UP series, UL and CSA certified, operates from 50V DC to 240V 50/60Hz. AP-MIL protectors, conforming to MIL-PRF-39019, undergo rigorous testing and are available in various configurations with or without auxiliary contacts.
