The Sensata APL/UPL series, including the APL1111-25978-101, are hydraulic magnetic circuit protectors. These devices provide reliable, low-cost power switching, circuit protection, and circuit control. The handle operates like an ON-OFF switch under normal load conditions, but the internal mechanism trips and forcibly returns the handle to the OFF position upon overload. The protector is "trip free," meaning the internal contacts will not remain closed during an overload, even if the handle is held in the ON position.
This specific model, APL1111-25978-101, features a lever actuator and is designed for panel mounting. It is a multi-pole assembly with 4 poles. The APL/UPL line offers various configurations, including different delays and ratings. These protectors are suitable for industrial, military, and information processing applications where precision operation is required.
IMPORTANT NOTICE: The APL/UPL series is a legacy product. No new design-in orders are being accepted, and Sensata Technologies recommends utilizing 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.
