No it doesn't 5 wires from the transformer in is active, neutral and earth out is active, neutral.If the contactor was made by Allen Bradley the C-12D10 info appears to say it's a 120v coil !
Its rated correctly for the 3-phase motor, but not for your single phase replacement.100-C12*10
Allen-Bradley MSC-C - contactors. The Allen-Bradley 100-C12*10 is a 3-phase IEC rated contactor used for the control of electric motors. It is rated 2 HP at 230V and 7.5 HP at 460V. Conforms to IEC/EN 60947-4-1 / 5-1 AB C12 10 AC Operating Coil Voltage: Options listed belowother 100-c contactors...controlparts.com
I think the coil current will be well under 1A, but I haven't seen its current consumption mentioned in the data sheets.
Does the existing low voltage transformer not have a primary tap for 220/240V as well as the 415V connection?
I haven't purchased the motor yet, the original 3pase was 1.1kw so I can drop the replacement to 1.1 to 1.4 kw which would be just under the 2hp rating (I would not have picked that up) thank you
