AIRPAX / SENSATA AP11R72103 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 a wide range of applications including communication, navigation, aircraft instrumentation, radar, and power supplies. The 'trip-free' action ensures the circuit won't remain closed during an overload, even with the handle in the ON position. The AP/UP series offers UL recognition and CSA certification, while AP-MIL protectors meet MIL-PRF-39019 standards. Multi-pole configurations allow for complex circuit protection schemes, such as series breakers, shunt configurations, and relay setups.
