Eaton BA2040 2 Pole 40 Amp Type BA Circuit Breaker Bolt In

The Eaton BA2040 is a two-pole, 40-amp Type BA circuit breaker with bolt-in mounting designed to provide dependable overcurrent protection for two circuits in compatible Eaton panelboards and enclosures across residential, commercial, and light-industrial electrical distributions. With a 40 A rating per pole and a 10 kAIC interrupt rating, it is capable of safely interrupting faults up to that level in compliant installations, helping to protect wiring, devices, and connected equipment. As part of Eaton's Cutler-Hammer BA family, this bolt-in device is engineered for secure mounting and reliable contact within Type BA panels, and the two-pole design ensures both conductors disconnect together during a fault. Use this BA2040 only in panelboards or enclosures specified by Eaton to accept BA-type bolt-in breakers, confirming that the application requires a 40 A, 10 kAIC Type BA solution and that the enclosure supports bolt-in BA devices.
