The Sensata APL/UPL series APL1-1REC4-62F-102-AM is a hydraulic magnetic circuit breaker designed for reliable power switching, circuit protection, and control. This single-pole unit has a current rating of 1A and a voltage rating of 277V.
It functions like an ON-OFF switch under normal load conditions, but its internal mechanism trips and opens the contacts upon overload, forcibly returning the handle to the OFF position. The breaker is 'trip free,' meaning the internal contacts will not remain closed during an overload, even if the handle is held in the ON position.
This circuit breaker features a lever actuator and is designed for panel mounting. It is suitable for industrial, military, and information processing applications where precision operation is required. The APL/UPL series is recognized by UL per UL STD. 1077 as supplementary protectors and certified by CSA per CSA STD. C22.2–No. 235.
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.
