Eaton FD3040BP10 3 Pole 40 Amp Circuit Breaker

Eaton FD3040BP10 is a 3‑pole, 40‑amp circuit breaker rated for use on three‑phase electrical systems up to 600 volts. This device belongs to the Eaton FD family and is intended to protect feeders and motor loads in industrial and commercial panels where reliable interruption of fault currents across all three hot legs is required. The 3‑pole configuration ensures simultaneous disconnect of all phases, helping maintain balanced protection for 3‑phase equipment in power distribution setups. With a 40‑A rating and a 600‑V maximum, the FD3040BP10 is selected when a dedicated 40‑amp, three‑pole protective device is specified by the system designer, and it should be installed only in compatible Eaton panels or enclosures that accept this model. Part number accuracy is important for replacement and compatibility, so use FD3040BP10 when the existing specification calls for a 40‑amp, 3‑pole FD series breaker.
