UPL1110-20458-1

The Sensata UPL1110-20458-1 is a hydraulic magnetic circuit breaker from the APL/UPL series. It functions as a reliable, low-cost power switching, circuit protection, and control device. The lever actuator operates similarly to an ON-OFF switch under normal load conditions. Upon overload, an 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 during an overload, even if the handle is held in the ON position.

Designed for industrial, military, and information processing applications, this circuit breaker is suitable for any situation requiring precision operation. It features a panel mount type and a lever actuator. The APL/UPL series offers various configurations, including series, shunt, and relay types, with a choice of delays and ratings. Multi-pole assemblies are also available.

IMPORTANT NOTICE: The APL/UPL series, including this part, is a legacy product. No new design-in orders are being accepted, and Sensata Technologies recommends utilizing the Airpax™ IAL series for new designs. Most versions of the APL family 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.
