APL111-1392-270

The Sensata APL111-1392-270 is a magnetic hydraulic delay circuit breaker from the APL/UPL series. This legacy product is designed for panel mounting and features a 3-pole configuration with a lever actuator. It provides reliable, low-cost power switching, circuit protection, and circuit control.

Upon overload, the internal mechanism trips, opens the contacts, and forcibly returns the handle to the OFF position. The protector is "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. This series 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.

While designed for industrial, military, and information processing applications, the APL series is suitable for any situation requiring precision operation. Most versions are recognized by UL per UL STD. 1077 as supplementary protectors and certified by CSA per CSA STD. C22.2–No. 235 as supplementary protectors.

IMPORTANT NOTICE: The APL/UPL is a legacy product and no new design-in orders are being accepted. Sensata Technologies recommends utilizing the Airpax™ IAL series for new designs.
