The Sensata APL/UPL Series APL111-1REC4-1817-11 is a hydraulic magnetic circuit protector designed for reliable power switching, circuit protection, and control. It features a lever actuator and a panel mount for easy integration into systems. This specific model is a 3-pole unit, meaning it can protect multiple circuits simultaneously.
This product is part of the APL/UPL line, which offers various configurations including series, shunt, and relay types with different delays and ratings. The protector operates like an ON-OFF switch under normal load conditions, but its internal mechanism trips and opens contacts upon overload, even if the handle is held in the ON position, ensuring safety.
It is important to note that the APL/UPL series is a legacy product line. Sensata Technologies is no longer accepting new design-in orders for these components and recommends the Airpax™ IAL series for new designs. While designed for industrial, military, and information processing applications, its precision operation makes it suitable for any situation requiring accurate circuit protection.
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. The UPL prefix designates versions certified by CSA.
