AIRPAX / SENSATA AP1161252 Magnetic Circuit Protector
The Airpax AP series are fully sealed, magnetic circuit protectors designed to provide power switching and accurate, reliable 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 various delays, these protectors are suitable for communication, navigation, aircraft instrumentation, radar, and power supplies. The 'trip-free' action ensures the circuit won't remain closed during an overload, and the sealed design maintains panel integrity. The UP series offers UL recognition and CSA certification, while AP-MIL protectors meet MIL-PRF-39019 standards for demanding applications.
