AIRPAX / SENSATA AP7161203 Magnetic Circuit Protector
The Airpax AP series magnetic circuit protectors combine power switching with accurate and reliable circuit protection, incorporating 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 versions for DC, 50/60Hz, or 400Hz applications, these protectors are designed to match specific requirements. 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 achieved through 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 for quality assurance. These protectors are commonly used in communication, navigation, aircraft instrumentation, radar, and power supplies.
