Heavy Electric bits 'n bobs

Hi all,

Any recommendations for a good British supplier of the more heavier side of the electronics components (like 1000A shunts, Allbright contactors etc) ?

Know plenty of the more usual electronic ranges, just struggling with the heavier-duty types.

Albright are a British company, I believe, and I've noticed that some of the bigger 4x4 and goods vehicle specialist places seem to stock their contactors, presumably for winch control purposes.

A quick Google on "Albright contactor" will throw up a few UK suppliers, or you can do a search on eBay. I'm pretty sure I bought my Albright from an eBay shop; the price was OK and they also stocked other stuff like big fuses I think.

Thanks Jeremy.
That's the contactors sorted. As the Allbright brand are sold all over the US, I thought they were American. Pleasant surprise to find they're in Surbiton !!!!

I do tend to spec stuff that's probably a bit more heavy duty than I need, but as the family motto is "If your going to have one, have a biggun", I find I'm struggling with a 1KA shunt (my traction voltage is 144v, 1231C controller, 500A max + a healthy margin - see family motto).
Ebay has some chinese ones with matching voltmeters but I'm keen to get one "locally" that isnt mental money.

A British company called Hobut (www.hobut.co.uk) make a range of shunts to go with their ammeters. I got a 300A one from them, but I expect they can do 500A or more.
(Surely there is no need to specify the system voltage for a shunt. It won't see that voltage because it is in series in your power circuit with only a minimal voltage drop across the shunt)

Cheers Jonathan,

I'll check them out.

I only mentioned the voltage along with the other things as I thought a 1kA shunt might be a bit over the top.
