AIRPAX / SENSATA AP12172F502 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 across a wide temperature range. Available in DC, 50/60Hz, or 400Hz versions, these protectors can be tailored to specific application requirements. The 'trip-free' action ensures the circuit won't remain closed during an overload, even with the handle in the ON position. Applications include communication, navigation, aircraft instrumentation, radar, and power supplies. The UP series, UL and CSA certified, offers an optional FM approval for petrochemical applications. AP-MIL protectors meet MIL-PRF-39019 standards and undergo rigorous testing for quality assurance.
