AIRPAX / SENSATA AP12142102 Magnetic Circuit Protector
The Airpax AP series are fully sealed, magnetic circuit protectors designed to combine power switching with accurate and 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. A key feature is the 'trip-free' action, ensuring the circuit opens even if the handle is held in the ON position. The AP series also offers waterproof panel integrity and meets MIL-STD-202 standards. The UP series, with UL and CSA certification, is similar in construction and principle, approved for operation at various voltages and currents. The AP-MIL protectors adhere to MIL-PRF-39019 standards and undergo rigorous testing for quality assurance.
