AIRPAX / SENSATA AP1171R41F153 Magnetic Circuit Protector
The Airpax™ AP series are fully sealed, magnetic circuit protectors designed to combine power switching with accurate and reliable circuit protection. 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. Available in DC, 50/60Hz, or 400Hz versions, they cater to diverse application requirements. Typical applications include communication, navigation, and aircraft instrumentation, radar, and power supplies. The AP-MIL protectors, produced to MIL-PRF-39019, undergo rigorous testing to maintain their Qualified Products Listing (QPL). Multi-pole configurations offer flexibility for protecting multiple circuits simultaneously, with options for series, shunt, or relay combinations.
