AIRPAX / SENSATA AP112R87059030 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. 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. The AP-MIL protectors adhere to MIL-PRF-39019 standards and undergo rigorous testing to maintain their Qualified Products Listing (QPL). Multi-pole configurations allow for complex circuit protection schemes, such as series breakers, shunt configurations, and relay circuits.
