AIRPAX / SENSATA AP1151103 Magnetic Circuit Protector

The Airpax™ AP series are fully sealed, magnetic circuit protectors designed to combine power switching with accurate and reliable circuit protection. A key feature is the inverse time delay and trip-free action, ensuring the circuit opens even if the handle is held in the ON position during an overload. Available in DC, 50/60Hz, or 400Hz versions, these protectors can be tailored to specific application requirements. The AP series is suitable for communication, navigation, and aircraft instrumentation, radar, and power supplies. The UP series offers UL recognition and CSA certification, while the AP-MIL protectors meet MIL-PRF-39019 standards for demanding applications. Multi-pole configurations allow for protection of multiple circuits with various combinations of series breakers, shunts, and relay contacts.
