The Airpax AP series magnetic circuit protectors offer a robust solution for power switching and circuit protection in demanding environments. Unlike thermal protectors, the AP maintains a consistent trip current across a wide temperature range. Available in various configurations with inverse time delays and a trip-free feature, it ensures safe operation by interrupting the circuit even when the handle is in the ON position. Typical applications include communication, navigation, aircraft instrumentation, radar systems, and power supplies. The UP series, with UL and CSA certification, provides similar functionality and is suitable for a range of voltage and current requirements. AP-MIL protectors meet MIL-PRF-39019 standards, ensuring high-quality performance and reliability for critical applications.
