AIRPAX / SENSATA AP12162102 Magnetic Circuit Protector
The Airpax AP series magnetic circuit protectors combine power switching with accurate and reliable circuit protection, incorporating inverse time delays and a trip-free feature. Unlike thermal protectors, the AP maintains a consistent trip current regardless of temperature. Available in various versions (DC, 50/60Hz, or 400Hz) with adjustable delays, these protectors cater to diverse application requirements. The 'trip-free' action ensures the circuit won't remain closed during an overload, even with the handle in the ON position. The AP12 two-pole unit provides protection for dual circuits, with a single toggle handle actuating both mechanisms. These protectors are commonly used in communication, navigation, aircraft instrumentation, radar, and power supplies. The AP-MIL variants adhere to MIL-PRF-39019 standards and undergo rigorous testing for quality assurance.
