The Sensata APL/UPL series APL111-1REC4-42-403-AM is a hydraulic magnetic circuit breaker designed for reliable power switching, circuit protection, and control. It features a 40A current rating and a 277V voltage rating across its 3 poles.
This circuit protector operates 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 contacts will not remain closed during an overload, even if the handle is held ON.
Designed for industrial, military, and information processing applications, this protector is suitable for any situation requiring precision operation. It is recognized by UL and certified by CSA as a supplementary protector. The APL/UPL series offers various configurations, including series, shunt, and relay types, with a choice of delays and ratings. Multi-pole assemblies allow for mixed current ratings, delays, and internal circuit configurations.
This specific model features panel mounting and a lever actuator. It is important to note that the APL/UPL series is a legacy product, and Sensata Technologies recommends the Airpax™ IAL series for new design-ins.
