AIRPAX / SENSATA AP121RC52102 Magnetic Circuit Protector

The Airpax AP series 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, a two-pole unit, provides protection for dual circuits with a single toggle handle, offering various combinations of ratings and delays. Multi-pole units feature rugged three-point panel mounting for enhanced shock and vibration resistance.
