AIRPAX / SENSATA AP12165103 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 across a wide temperature range. 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. Applications include communication, navigation, aircraft instrumentation, radar, and power supplies. The UP series, with UL and CSA certification, is suitable for various voltage and current ratings. AP-MIL protectors adhere to MIL-PRF-39019 standards and undergo rigorous testing for quality assurance. Multi-pole configurations allow for complex circuit protection schemes, such as series breakers, shunt configurations, and relay systems.
