The Sensata APL/UPL series, including the APL1-1-69-203-AM, are hydraulic magnetic circuit protectors designed for reliable power switching, circuit protection, and control. This specific model is rated for 20A and 277V, with a single pole configuration and a lever actuator for manual operation.
Designed for panel mounting, this circuit protector functions like an ON-OFF switch under normal load conditions. Upon detecting an overload, its internal mechanism trips, opening the contacts and forcibly returning the handle to the OFF position. The 'trip-free' design ensures the internal contacts cannot be held closed during an overload, even if the handle is manually held in the ON position.
This product is part of a legacy line. Sensata Technologies recommends the Airpax™ IAL series for new designs. While designed for industrial, military, and information processing applications, its precision operation makes it suitable for various systems requiring reliable circuit protection.
