AIRPAX / SENSATA AP12162103 Magnetic Circuit Protector
The Airpax AP series are fully sealed, magnetic circuit protectors designed to provide power switching and accurate, reliable circuit protection. Unlike thermal protectors, the AP maintains a consistent trip current across a wide temperature range. These protectors offer inverse time delays and a “trip-free” action, ensuring the circuit opens even when the handle is held in the ON position. They are 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. AP-MIL protectors meet MIL-PRF-39019 standards and undergo rigorous testing. Multi-pole units offer flexible configurations, such as series breakers, shunt circuits, and relay options, catering to diverse industrial needs.
