What this coil fits
The S-N11-COILAC120V is the service coil for the Mitsubishi S-N11 contactor — if the original coil opens or the line voltage changes, this is the drop-in replacement. It carries a 120V AC coil voltage, which matches the standard control-voltage tap in North American and many export panels.
What you need to know before ordering
This is the coil only — no contactor base, no auxiliary blocks. It mounts directly onto the S-N11 contactor frame. The 120V AC rating is the operating coil voltage; confirm your control transformer taps match before you pull the old coil.
