UPL111-27227-1

The Sensata UPL111-27227-1 is a 3-pole hydraulic magnetic circuit breaker from the APL/UPL series. It is designed for panel mounting and features a lever actuator for circuit control. This product is identified as a legacy item, and new design-in orders are not being accepted.

This circuit protector provides reliable power switching, circuit protection, and control. Upon overload, the internal mechanism trips, opening the contacts and forcibly returning 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.

While specific electrical ratings and trip times are not detailed here, 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. The product is recognized by UL per UL STD. 1077 as supplementary protectors and certified by CSA per CSA STD. C22.2–No. 235 as supplementary protectors.

Sensata Technologies recommends utilizing the Airpax™ IAL series for new designs, as the APL/UPL series is a legacy product. For existing designs requiring specifications, refer to the datasheet.
