AIRPAX / SENSATA AP7151203 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 various versions (DC, 50/60Hz, or 400Hz) with adjustable delays, these protectors are suitable for diverse application requirements. A key feature is the 'trip-free' action, ensuring the circuit opens even when the handle is held in the ON position. The AP series is also known for its waterproof panel integrity, achieved through an O-ring bushing seal and silicon rubber gland. The UP series, with UL and CSA certification, is approved for operation at various voltages and currents, and the AP-MIL protectors meet MIL-PRF-39019 standards. Typical applications include communication, navigation, aircraft instrumentation, radar, and power supplies.
