The Sensata APL111-5-61-102 is a hydraulic magnetic circuit breaker from the APL/UPL series. This legacy product offers reliable, low-cost power switching, circuit protection, and circuit control.
Key electrical specifications include a current rating of 1A and a voltage rating of 277V. It is a 3-pole device with a magnetic (hydraulic delay) breaker type and a lever actuator. The mounting type is panel mount, suitable for industrial, military, and information processing applications.
This circuit protector is designed to be trip-free, meaning the internal contacts will not remain closed in the presence of an overload, even if the handle is held in the ON position. The APL/UPL line offers various configurations, including multi-pole assemblies with mixed current ratings, delays, and internal circuit configurations. While designed for precision operation, it is noted as a legacy product with no new design-in orders accepted. Sensata Technologies recommends the Airpax™ IAL series for new designs.
