The Sensata UPL11-21781-1 is a hydraulic magnetic circuit protector from the APL/UPL series. This legacy product features a 2-pole configuration and a lever actuator for manual operation. It is designed for panel mounting, providing reliable, low-cost power switching, circuit protection, and circuit control.
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. This series offers various configurations, delays, and ratings, suitable for industrial, military, and information processing applications where precision operation is required.
This product is recognized by UL per UL STD. 1077 as a supplementary protector and certified by CSA per CSA STD. C22.2–No. 235. Note that this is a legacy product, and no new design-in orders are being accepted. Sensata Technologies recommends utilizing the Airpax™ IAL series for new designs.
