BR240 - 40 Amp Circuit Breaker

BR240 - 40 Amp Circuit Breaker

The Eaton BR240 is a 40 Amp, two-pole circuit breaker for Eaton Type BR loadcenters. It is commonly used on 120/240V circuits serving air conditioners, heat pumps, electric ranges, water heaters, compressors, and other equipment that requires a 40 Amp two-pole breaker.

You'll find this breaker in residential panels, apartment buildings, workshops, retail spaces, offices, and light commercial properties. Common applications include HVAC equipment, electric heating systems, water heaters, pumps, compressors, and other dedicated 240-volt loads.

Many BR240 breakers remain in service for years in properly maintained electrical systems, which is one reason Eaton's Type BR line continues to be widely used in existing installations.
