WEG BCA4-40 Replacement Coil for CWM Contactors — 32–40 A (CWM32–CWM40)
Genuine WEG BCA4-40 AC replacement coil for WEG CWM-line IEC contactors rated 32 through 40 amps (CWM32 and CWM40, plus CWMC32). When a contactor stops pulling in, hums, or chatters, a worn or burned-out coil is the usual cause — and swapping the coil is far cheaper than replacing the whole contactor.
Select your control voltage from the drop-down. AC and DC coils are not interchangeable, so order the AC coil that matches your control circuit voltage.
