APL1-1-41-102

The Sensata APL1-1-41-102 is a hydraulic magnetic circuit breaker from the APL/UPL series. This legacy product is designed for reliable power switching, circuit protection, and circuit control. It operates as a switch under normal load conditions, but its internal mechanism trips and opens the contacts upon overload, forcibly returning the handle to the OFF position. The protector is trip-free, ensuring contacts do not remain closed during an overload.

Key electrical specifications include a current rating of 1A and a voltage rating of 277V. The breaker type is magnetic with a hydraulic delay, and it features a lever actuator. This model is a single-pole unit, suitable for various industrial, military, and information processing applications where precision operation is required. The mounting type is panel mount.

This product line offers many configurations, including series, shunt, and relay types with a choice of delays and ratings. Multi-pole assemblies are also available, combining multiple poles with linked handles and coupled trip mechanisms. A fault in any protected circuit will open all poles simultaneously. The APL/UPL family is recognized by UL per UL STD. 1077 as supplementary protectors and certified by CSA per CSA STD. C22.2–No. 235 as supplementary protectors.
