HI Folks
As the subject says - can't seem to find a contact that operates off
12volts on the coil, and is rated to switch 40+ amps @ 240v a/c.

Does such a thing exist - or do I have to use a a slave relay from the
12v to switch a 240v coil?

Thanks
Adrian

but you don't want to be paying their prices!

There are plenty of similar contactors, from many manufacturers, that
are rated the same or higher.

Thanks Steve
No - I certainly don't want to be paying that sort of money (£138 !) -
only needs to be single-pole anyway...

I did the obligatory search on Google, and trawled CPC / Farnell without
much success..

I think it'll turn out a lot cheaper in the long run to use the 12v to
switch a little din-mounted relay, and use that to switch the 240v to a
£35 40A contactor. Also kinder on the circuit that's driving it..

Thanks
