AIRPAX / SENSATA AP121R62F252 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, aircraft instrumentation, radar, and power supplies. The UP series, with UL and CSA certification, is similar in construction and operating principle, approved for operation at various voltage and current levels. AP-MIL protectors adhere to 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.
