APL111-2REG4-27495-2

The Sensata APL111-2REG4-27495-2 is a 3-pole magnetic hydraulic delay circuit breaker designed for reliable power switching, circuit protection, and control. It features a lever actuator for manual operation, similar to an ON-OFF switch. In the event of an overload, the internal mechanism trips, opening the contacts and forcibly returning the handle to the OFF position. This 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 circuit breaker is suitable for industrial, military, and information processing applications where precision operation is required. It is designed for panel mounting, offering a secure and stable installation. The APL/UPL series, to which this part belongs, is recognized by UL per UL STD. 1077 as supplementary protectors and certified by CSA per CSA STD. C22.2–No. 235.

While this specific part number is APL111-2REG4-27495-2, the APL/UPL line offers various configurations, including series, shunt, and relay types with a choice of delays and ratings. Multi-pole assemblies are available with a mix of current ratings, delays, and internal circuit configurations, allowing for combinations up to nine poles. This part is noted as a legacy product, and new design-in orders are not being accepted.
