The Sensata APL11-1-51F-502 is a two-pole hydraulic magnetic circuit breaker designed for reliable power switching and circuit protection. It offers a current rating of 5A and a voltage rating of 277V.
This circuit breaker features a lever actuator for manual operation and is designed for panel mounting. The hydraulic delay mechanism ensures precise tripping characteristics upon overload conditions, providing protection similar to an ON-OFF switch. The protector is trip-free, meaning the internal contacts will open even if the handle is held in the ON position during an overload.
This APL/UPL series product is recognized by UL per UL STD. 1077 as a supplementary protector and certified by CSA per CSA STD. C22.2–No. 235. It is suitable for industrial, military, and information processing applications where precision operation is required.
Important Note: The APL/UPL series is a legacy product. Sensata Technologies recommends utilizing the Airpax™ IAL series for new design-ins.
