AIRPAX / SENSATA AP1121R72F501 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. These protectors are available in DC, 50/60Hz, or 400Hz versions with various delay options to suit specific application needs. A key feature is the “trip-free” action, ensuring the circuit opens even if the handle is held in the ON position. Applications include communication, navigation, aircraft instrumentation, radar, and power supplies. The UP series, UL recognized and CSA certified, offers an optional FM approval for petrochemical applications. AP-MIL protectors meet MIL-PRF-39019 standards and undergo rigorous testing for quality assurance.
