The Sensata UPL11-34178-20 is a hydraulic magnetic circuit breaker from the APL/UPL series, featuring a lever actuator and panel mount design. This unit has two poles and is suitable for applications requiring reliable power switching, circuit protection, and control.
This circuit breaker operates similarly to an ON-OFF switch under normal load conditions. Upon detecting an overload, its internal mechanism trips, opening the contacts and forcibly returning the handle to the OFF position. It is designed to be 'trip free,' meaning the internal contacts will not remain closed during an overload, even if the handle is held in the ON position.
Important Note: The APL/UPL series, including this part number, is a legacy product. Sensata Technologies no longer accepts new design-in orders for these components and recommends the Airpax™ IAL series for new designs. While designed for industrial, military, and information processing applications, its legacy status should be considered for any new projects.
Key specifications include a panel mount type and a lever actuator. The product is recognized by UL per UL STD. 1077 as a supplementary protector and certified by CSA per CSA STD. C22.2–No. 235.
