AIRPAX / SENSATA AP1151203 Magnetic Circuit Protector

The Airpax AP series hydraulic magnetic circuit protectors combine power switching and accurate, reliable circuit protection with inverse time delays and trip-free features. Unlike thermal protectors, the AP maintains a consistent trip current across a wide temperature range. Available in DC, 50/60Hz, or 400Hz versions with various delays, these protectors are suitable for communication, navigation, aircraft instrumentation, radar, and power supplies. The 'trip-free' action ensures the circuit won't remain closed during an overload. The AP12 two-pole unit provides protection for dual circuits, while the AP112 three-pole unit protects three circuits simultaneously. Multi-pole units offer flexible configurations with series, shunt, and relay options.
