AIRPAX / SENSATA AP7161802 Magnetic Circuit Protector
The Airpax™ AP series are fully sealed, magnetic circuit protectors that combine power switching and accurate, reliable circuit protection with inverse time delays and trip-free features. Unlike thermal protectors, the AP maintains a consistent trip current across a wide temperature range. Available in various DC, 50/60Hz, or 400Hz versions with adjustable delays, the AP is suitable for diverse applications. The 'trip-free' action ensures the circuit won't remain closed during an overload, even with the handle in the ON position. Waterproof integrity is maintained by an O-ring bushing seal and a silicon rubber gland. The UP series, UL recognized and CSA certified, offers an optional FM approval for petrochemical applications. AP-MIL protectors meet MIL-PRF-39019 standards and undergo rigorous testing. Typical applications include communication, navigation, aircraft instrumentation, radar, and power supplies.
