Eaton BR240 Circuit Breaker

The Eaton BR240 is a two-pole, 40-amp circuit breaker from Eaton Cutler-Hammer, built as a Type BR device with a C240 frame. This breaker provides overcurrent protection by interrupting current when a fault or overload occurs, automatically opening both hot conductors in its 2-pole configuration to shield wiring and connected equipment. As part of the BR family, the BR240 reflects Eaton's standardized form factor and labeling, making it recognizable in panels and enclosures that specify BR-type breakers. The model BR240, along with the C240 frame designation, identifies its size and mounting footprint and helps ensure correct fit in compatible electrical distribution equipment. Key specifications to note are: 2-pole, 40 A, Type BR, and the C240 frame. Use cases generally include protection for branch circuits and feeders where a BR-series breaker is specified by the panel manufacturer or electrical code, keeping circuits from drawing unsafe currents and aiding in safe maintenance by allowing a single-point shutdown of the protected circuit.
