yeah there are few size you can use but what size starter you have it is #2 or #3 starter size because the reason why i asked here because those size starter they dont use the same size coil they will useally rated in X of VA

but i can give you a rough idea the control transfomer size

120X240 volt primary with 24 volt secondary with 24 volt coil which it very common with alot of the motor starter used this

the typical size useally about 150 VA size for #2 and smaller but for #3 and larger i useally bump up to 200 VA for it due the coil size

or other option you can do is have 240v primary transformer with 120v secondarly volt and use the stock 120 v coil

those two options you can do

if you add the control transformer IMO it will be wise idea to add a fuse to this as well

Merci , Marc

just a quick question you mention air commpressor right ?? and have the pressure switch right ??

if so i can tell ya the way it connected.

and i think you can get 240 volt coil it somehow cheaper and quicker than try to wired up the transformer set up with 24 volt coil

the 240 volt coil is pretty common item you should have not much issuse getting this one at all

Merci, Marc

let me add this connection dig.

just hit the word " connection dig."

this is pretty common way of connection but just one warning some connection for coil and O/L's are not the same so use your judgement on this one

are you talking about this starter ??

the reason why i am doubling checking this one

starter

just take your pointer and click on the word " starter " it will show the image of this one and let me know ASAP

Merci, Marc

how you did oringally wired the coil ?? i am supecting that if you actally have real single phase supply or 3 phase supply it will tell the diffrnece there

and with 10 HP single phase motor that will draw a bit of current IIRC it will be about 50 amp or so @240 volts

Thats the one frenchelectrican and its single phase. I wired from L1 to a switch then to the pressure sw then back to A1.L2 to 96 then 95 to a2. I cant find the paper i drew out.
