AIRPAX / SENSATA AP17171203 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, the AP series caters to diverse application requirements. A key feature is the 'trip-free' action, ensuring the circuit opens even when the handle is held in the ON position. These protectors are suitable for communication, navigation, aircraft instrumentation, radar, and power supplies. The UP series, recognized by UL and CSA, offers similar functionality with approvals for specific voltage and current ratings. The AP-MIL protectors, manufactured to MIL-PRF-39019, undergo rigorous testing to maintain their Qualified Products Listing (QPL).
