APL111-22712-2

The Sensata APL111-22712-2 is a magnetic hydraulic delay circuit breaker. It features a 3-pole configuration and is operated by a lever actuator. This model is designed for panel mounting, offering reliable circuit protection for various applications.

The APL/UPL series, to which this part belongs, provides low-cost power switching, circuit protection, and control. The internal mechanism trips upon overload, forcibly returning the handle to the OFF position. The protector is trip-free, meaning the internal contacts will not remain closed under overload conditions, even if the handle is held in the ON position. This series offers various configurations, including series, shunt, and relay types, with a choice of delays and ratings. Multi-pole assemblies are available with mixed current ratings, delays, and internal circuit configurations, supporting combinations up to nine poles.

This circuit protector is suitable for industrial, military, and information processing applications where precision operation is required. It is recognized by UL per UL STD. 1077 as a supplementary protector and certified by CSA per CSA STD. C22.2–No. 235 as a supplementary protector.
