The Cutler‑Hammer BR240 2‑Pole 40 Amp circuit breaker is a robust thermal‑magnetic breaker designed to provide dependable overcurrent protection for residential and light commercial electrical systems. Engineered for use in Type BR load centers and panelboards, this breaker helps protect electrical wiring, equipment, and connected loads from potential damage caused by overloads and short‑circuit events.

As part of the well‑established BR breaker family, the BR240 offers consistent tripping performance and long‑term reliability. Its two‑pole configuration provides a common disconnect for both ungrounded conductors, making it ideal for 240‑volt applications and equipment circuits that require simultaneous disconnection. The plug‑on mounting design allows for quick installation while maintaining a secure mechanical and electrical connection within compatible panels.

Frequently used in applications such as HVAC equipment, electric water heaters, ranges, and other medium‑to‑high load circuits, the Cutler‑Hammer BR240 breaker is trusted by electricians, contractors, and facility maintenance professionals who require proven performance and code‑compliant circuit protection.
