Description
The Schneider Electric (Square D) B11.5 Thermal Unit is a melting alloy overload element designed, for motor protection by responding to excessive current conditions. It operates within a calibrated current range of approximately 7.84 to 8.47 amps and is built for plug-in mounting within compatible starter assemblies. The unit reacts to heat generated by overcurrent conditions, and initiates circuit interruption to support controlled electrical operation. Installed in motor starter and control assemblies in HVAC systems it operates as a protective thermal element that helps regulate motor load conditions, and maintain stable equipment operation.
