Anyone know what brand these terminals are?

Anyone know what brand these terminals are please?!

Need to link the mains out to another box, so need additional terminals and push-in links, but I forgot to check the brand before I left!

Cheers!

They look like an Entrelec terminal to me, but not entirely sure which model.
The grey end plate on the brown terminal has info printed on it.

I believe not but...

I was going to say the same thing.

I have a box of very similar shaped terminals by entrelec.

BTW whoever built that assembly seems to have been cuting corners. There don't seem to be any end stops to prevent the terminals sliding along the rail and seperating (which given that din rail terminals are only insulated on one side is a rather suboptimal situation)

At least it's an earth terminal at the end although with nothing connected to the bottom terminal rather than a live with exposed terminals to the side!

After looking through a box of random terminals earlier today I have 4 different designs of Entrelec, I came back here to report I have a couple of ABB ES4's. I see in EFL's picture the markings are different to my older products and now show both names.

I assume there has been a merger of some sort

The live terminal has an end plate to provide insulation but I agree there should be end stops.

I take it you are aware that earth terminals make contact with the DIN rail.

The earth terminals can be used in place of end stops, not as good as a screwed stop but that's what the manufacturers say.

A lot depends on the make, some have a really good screw clamp (such as Wiedmuller) and I tended to use them instead of end stops until the price went through the roof... one can never have too many earths . However on some the earth connexion is only just strong enough to break through the coating.

EDIT: It also depends on the end stop, some are not fit for purpose and the matching earth terminal offers a better solution.

Slightly OT but did you know that schnieder have just revamped all their pilot lights?
Now only white LED's are available for use on the new darker coloured pilot lights.
Use a new LED on the old pilot and it's all washed out.

I use mainly Allen Bradley, Weidmuller and Entrelec terminals although we got some Wago ones in today, someone thought it would be a good idea except now we cannot print terminal markers without buying wago's printer DOH.

Did the OP manage to find some more terminals?

That occurred on some a while back. It's possible Idec, the telltale being the yellow back end changed to black (could have been vice versa) and some additional internal filters were quickly made available but the blue's didn't get proprly resolved.

I'm getting out of touch to be honest, I haven't done any significant panel work for best part of 7 years. and I claim it's retirement!

I don't know if I've ever handled AB (as opposed to ABB) terminals but looking on line I find this range;

Which I know under a name under a Spanish or Italian name, something like 'Conta' but it's been too far back to know and also Weidmuller but I know not if they are identical. The earth terminal arrangement was a bit fiddly but very effective and secure once tightened and habitually used insted of end stops.

I know how quickly things changed in the 15 previous years, for a start there were 4 enclosure colour changes and all of a sudden I realise the RAL numbers are no longer in my recall ability, I'll hazard a guess at RAL3550 (but it could easily be barbie pink). Almost all of my panel work has been as a self employed subby and working for maybe 20 different companies encountered a vast selection of different makes and ranges of products and the development of those as mergers occurred. So much so that much of my identification of products, particularly where I do post install, and later, modifications, has been visual and often resulting in a different makes clone (in OP instance my identification of the item by comparing with a couple of leftover terminals had been ABB but I clearly see the markings have changed and now include Entrelec).
The changeover between these 2 Omron styles seemed to be instant between panels for a job.

and if anyone had suggested the change had occurred and how quickly I'd have been tempted to say they were wrong.
Getting back to end stops; I always found this style to be about as useful as a chocolate teapot in hell.

This one happens to be Cabur (Italian) but other similar makes exist.
I found the angled clamp plate to be ineffective at clamping on one edge of the DIN rail and if it did do so it had the effect of lifting the 'hook' part on the other edge away from the rail. The 'correct operation' was supposedly to clamp against the outsides of the rail but a fairly soft plastic moulding and a warm vibrating panel and time simply don't mix.

He thanked early replies but no follow-up posts.

I did thanks!

They're a stock item at RS, and I realised that the manufacturers of these boxes had installed spare terminals that weren't needed. I repurposed them, and ordered the jumpers from RS.

To be honest I wasn't aware that end stops existed or were needed!

In this case the box will never be opened up while energised so I'm not going to lose sleep over it, but I'll keep an eye out for end stops in future
