AIRPAX / SENSATA AP112161203 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. Typical applications include communication, navigation, aircraft instrumentation, radar, and power supplies. The AP series is available in DC, 50/60Hz, or 400Hz versions, and the AP-MIL variant adheres to MIL-PRF-39019 standards, ensuring a qualified products listing. Multi-pole configurations allow for protection of multiple circuits with various coil combinations and auxiliary contacts.
