AIRPAX / SENSATA AP6151203 Magnetic Circuit Protector

The Airpax AP series are fully sealed, magnetic circuit protectors designed to combine power switching with accurate and reliable circuit protection. These protectors offer inverse time delays and a trip-free feature, preventing the circuit from remaining closed during an overload, even with the handle in the ON position. Available in DC, 50/60Hz, or 400Hz versions, they can be tailored to specific application requirements. The AP series is suitable for communication, navigation, aircraft instrumentation, radar, and power supplies. The UP series, with UL and CSA certification, is similar in construction and operating principle, approved for various voltage and current ratings. AP-MIL protectors meet MIL-PRF-39019 standards and undergo rigorous testing for quality assurance. Multi-pole configurations offer flexibility for protecting multiple circuits simultaneously.
