AIRPAX / SENSATA AP12372203 Magnetic Circuit Protector
The Airpax AP series are fully sealed, magnetic circuit protectors designed to provide power switching and accurate, 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. They are suitable for communication, navigation, aircraft instrumentation, radar, and power supplies. The AP/UP series, with UL and CSA certifications, is available in single-pole units and offers an optional FM approval for petrochemical applications. AP-MIL protectors adhere to MIL-PRF-39019 standards and undergo rigorous testing for quality assurance.
