AIRPAX / SENSATA AP12172F103 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. The AP series is suitable for communication, navigation, aircraft instrumentation, radar, and power supplies. The UP series, with UL and CSA certification, operates at various voltages and currents. AP-MIL protectors meet MIL-PRF-39019 standards and undergo rigorous testing for quality assurance. Multi-pole configurations offer flexibility for protecting multiple circuits simultaneously, with options for series, shunt, or relay combinations.
