The Sensata APL/UPL series APL1-1REC4-52-104-M is a hydraulic magnetic circuit breaker designed for reliable power switching and circuit protection. It features a 100A current rating and a 277V voltage rating, with a single pole configuration and a lever actuator.
This is a legacy product, designated as 'Existing Design-In Only'. Sensata Technologies recommends the Airpax™ IAL series for new designs. The APL/UPL series provides dependable, low-cost circuit control, functioning like an ON-OFF switch under normal load conditions. Upon overload, the internal mechanism trips, opening the contacts and forcibly returning the handle to the OFF position. It is 'trip free', meaning the contacts will not remain closed under overload conditions, even if the handle is held ON.
Designed for industrial, military, and information processing applications, this circuit breaker is suitable for systems requiring precise operation. It is recognized by UL and certified by CSA as a supplementary protector. The unit features a panel mount design for easy integration into control panels.
