The Sensata APL/UPL series APL1-1-53-503 is a hydraulic magnetic circuit protector designed for reliable power switching, circuit protection, and control. It features a 50A current rating and a 277V voltage rating, with a single pole configuration and lever actuator.
This is a legacy product, and Sensata Technologies recommends the Airpax™ IAL series for new designs. The APL/UPL series provides low-cost power switching and circuit control, similar to an ON-OFF switch. Upon overload, the internal mechanism trips, opening the contacts and forcibly returning 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.
Designed for industrial, military, and information processing applications, this circuit protector is suitable for any situation requiring precision operation. It is recognized by UL per UL STD. 1077 as a supplementary protector and certified by CSA per CSA STD. C22.2–No. 235. The mounting type is panel mount.
