This model was likely common 25 years ago, in Europe (France). I don't know the brand and cannot find any reference based on pictures.

The plastic case is fully transparent, no levers, only a slat. The top of the case is trapezoid. I'm not sure of the markings, perhaps 600M IDEAL 85.

I've two questions for someone who already saw this beast:

  • What are the brand, and model if possible.
  • How do you properly unplug the wires? (I've seen advice to just turn the wire until it is loose...)

    If not short of wire, a pair of wire cutters will remove the wires fast, with the power off. There might be a tiny slot/opening to push a tool/tiny screwdriver in, to release the wire/s. Somethings do have a bad design when it comes to repairs or a use once only design. Have a machine with one bolt/nut in a bad place to undo. Most times it is faster to use a torch to cut the nut off.

  • @crip659: Thanks. I cannot check at the moment, but I remember seeing a tiny hole next to the inputs for the wires. Cutting the wires is not possible as I need to understand the cause of a voltage leakage, and I'll likely have to connect/unconnected several times different portions. After it is repaired, I plan to change the connectors for something reusable.

    I would have reusable ones handy in case those are single use. We have push in connectors on outlets/switches in the US, but on the cheaper ones they are/should only be used once. Good electricians don;t like them, unless being paid to change the wires to the screws.

    The brand is all-but-certainly Ideal®, based on the marking, and the fact that Ideal is a maker of wire connection products including some push-in wire connectors; but I have no idea exactly what they commonly sold in France 25 years ago. I preferred wire-nuts (Marrettes) which they also make to these things when the version of these things they sold here was common in the USA.

That appears to be an early version of the product Ideal® currently calls In-Sure Push In (in English, anyway) and the current 88/87 model numbers suggest that 85 is a plausible model number. Or perhaps 35, given the current 33, 34 & 39.

600M is probably a misreading of the V for M in the 600Volt rating.

Possibly the France version of their site has the exact match, or possibly the old ones are no longer made in exactly that style/model number. The 34 instructions for wire removal are twist and pull, and not to re-use on stranded wire at all, and to re-strip solid wire, so moving immediately to a "removable-without-damage" lever type would be advisable rather than reusing these. The 88 instructions don't mention removal at all.

  • Thanks for all the useful details. My model seems older than the Internet in the end. You must be right for 600V.

  • The internet is fairly old, (quite a bit more than 25 years) the stuff that companies show on their websites, on the other hand, has a very sort expiration time, in many/most cases.
