AIRPAX / SENSATA AP12151103 Magnetic Circuit Protector

The Airpax AP series magnetic circuit protectors combine 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 regardless of temperature. Available in DC, 50/60Hz, or 400Hz versions, 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.
