AIRPAX / SENSATA AP17165202 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 regardless of temperature. Available in DC, 50/60Hz, or 400Hz versions with adjustable delays, these protectors cater to specific application requirements. The 'trip-free' action prevents continued operation during an overload, and the sealed design ensures waterproof panel integrity. Typical applications include communication, navigation, aircraft instrumentation, radar, and power supplies. The UP series offers UL and CSA certification and an optional FM approval for petrochemical applications. AP-MIL protectors adhere to MIL-PRF-39019 standards, ensuring a rigorous production and testing program.
