The Sensata APL/UPL series APL111-1-61-203 is a hydraulic magnetic circuit breaker with a 20A current rating and a 277V voltage rating. This 3-pole breaker is designed for panel mounting and features a lever actuator. It provides reliable, low-cost power switching, circuit protection, and circuit control.
Upon overload, the internal mechanism trips, opens the contacts, and forcibly returns the handle to the OFF position. The protector is 'trip free,' meaning the internal contacts will not remain closed in the presence of an overload, even if the handle is held in the ON position. The APL/UPL line offers various configurations, including series, shunt, and relay types, with a choice of delays and ratings. Multi-pole assemblies are available with a mix of current ratings, delays, and internal circuit configurations.
This legacy product is suitable for industrial, military, and information processing applications where precision operation is required. 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.
