Schneider Electric C114.0 Thermal Overload Relay

Schneider Electric C114.0 is a C Series Class 20 manual-reset thermal unit that serves as the thermal protection element in Square D overload-relay assemblies used to guard motors against overheating. As a thermal model of motor heating, it responds to excess current by driving the associated relay to trip, then requires a manual reset after the motor and unit have cooled. The C114.0 designation identifies this specific manual-reset unit within the Class 20 family, designed to work with standard Square D/Schneider Electric motor-control hardware, including 9065-style overload relays and compatible contactors. Typical deployments include conveyors, pumps, fans, and other industrial machinery where motor overload protection and a resettable trip are desired, with the thermal unit chosen to match the protection scheme defined by the accompanying overload relay and controller.
