WEHRLE Relay info required

[retepnikrap]

Hi

I have a fuse box with a number of these relays in 'WEHRLE 20 200 100 A - 12V / 30A' . I have a couple of spare relay slots which I want to use for accessories and would like to use the same relays to avoid any incompatibility issues, anyone know where I can get them? Tried ebay but can't find ones with matching numbers, what does the numbers '20 200 100 A' signify? I have seen a '20 400 100 A' on ebay but not sure how if at all differs from my '20 200 100 A' relay.

If I need to get a different type can anyone recommend one which will do exactly the same job (type, name, model) would be appreciated. I will be fusing them at around 10A and 20A, thank you in advance.

That looks like a fairly standard Automotive relay to me, no reason why they'd need to match for any sort of compatibility.

For example http://www.autoelectricsupplies.co.uk/product/172/...

If you want them to match for other reasons then fair enough, I think we can all get on board with that sort of care and attention but there's no real reason they need to.

The important numbers are 12v and 30A, i.e it's a 12 volt relay with 30 amp contacts.
The other numbers on the side are probably just a part number.
The numbers on the bottom are a standard pin layout for a single pole, single throw relay.

This is an equivalent which will fit the same socket and work the same way: http://www.ebay.co.uk/itm/4-PIN-12V-30-A-RELAY-30-...

(The link by the previous poster is not the same type of relay - that's a single pole, double throw type)
