Coil for the S-N21 contactor
The Mitsubishi Electric S-N21-COILAC400V is the replacement coil for the S-N21 series contactor, specified for a 400V AC coil supply. It is the service part that swaps into the contactor frame when the original coil fails or a voltage change is needed.
Compatibility and fit
This coil is designed to mount directly onto the S-N21 contactor's magnet assembly. The mechanical interface and coil termination match the S-N21 frame; no adapter or modification is required.
