AIRPAX / SENSATA AP121RC51F252 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 delay options, the AP adapts to specific application needs. 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 suitable for communication, navigation, aircraft instrumentation, radar, and power supplies. The UP series, a UL recognized and CSA certified variant, offers an optional FM approval for petrochemical applications. AP-MIL protectors adhere to MIL-PRF-39019 standards and undergo rigorous testing for quality assurance.
