AIRPAX / SENSATA AP112142103 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. Available in various versions and with adjustable delays, these protectors are suitable for diverse applications. A key feature is the “trip-free” action, which ensures the circuit opens even if the handle is held in the ON position. The AP series is also available as the UP series, recognized by UL and CSA for operation at various voltages and currents, and the AP-MIL series, produced to MIL-PRF-39019 standards. Multi-pole configurations offer flexibility for protecting multiple circuits simultaneously.
