AIRPAX / SENSATA AP12165751 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. These protectors are available in DC, 50/60Hz, or 400Hz versions with various delay options to suit specific application needs. A key feature is the “trip-free” action, ensuring the circuit won't remain closed during an overload. Applications include communication, navigation, aircraft instrumentation, radar, and power supplies. The UP series, recognized by UL and CSA, offers similar functionality with approvals for various voltage and current ratings, and an optional FM approval is available for petrochemical applications. AP-MIL protectors adhere to MIL-PRF-39019 standards and undergo rigorous testing for quality assurance.
