AIRPAX / SENSATA AP12172103 Magnetic Circuit Protector

The Airpax AP series magnetic circuit protectors combine power switching with accurate and reliable circuit protection, incorporating inverse time delays and trip-free features. Unlike thermal protectors, the AP maintains a consistent trip current regardless of temperature. Available in DC, 50/60Hz, or 400Hz versions with various delays, these protectors are suitable for communication, navigation, aircraft instrumentation, radar, and power supplies. The 'trip-free' action ensures the circuit won't remain closed during an overload. The AP series is also available as the UP series, recognized by UL and CSA, and the AP-MIL series, produced to MIL-PRF-39019 standards for demanding applications. Multi-pole configurations offer flexibility for protecting multiple circuits simultaneously.
