The Sensata APL/UPL series, including the UPL1-2238-7, are hydraulic magnetic circuit protectors designed for reliable power switching, circuit protection, and control. This specific model is a single-pole unit with a lever actuator and is designed for panel mounting.
These protectors function similarly to an ON-OFF switch under normal load conditions. Upon detecting an overload, an internal mechanism trips, opening the contacts and forcibly returning the handle to the OFF position. The "trip free" design ensures the internal contacts cannot remain closed during an overload, even if the handle is held in the ON position.
While designed for industrial, military, and information processing applications, the APL/UPL series is suitable for any situation requiring precision operation. It is important to note that the APL/UPL series is a legacy product, and no new design-in orders are being accepted. Sensata Technologies recommends the Airpax™ IAL series for new designs.
Most versions of the APL family are recognized by UL per UL STD. 1077 as supplementary protectors and certified by CSA per CSA STD. C22.2–No. 235 as supplementary protectors.
