AIRPAX / SENSATA AP12172F202 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 offer inverse time delays and a “trip-free” action, ensuring the circuit opens even when the handle is held in the ON position. They are suitable for communication, navigation, aircraft instrumentation, radar, and power supplies. The UP series, recognized by UL and CSA, is similar in construction and principle, while the AP-MIL protectors adhere to MIL-PRF-39019 standards for demanding applications.
