At the year 2024, in China, a new design of Mini Quick connect terminal was born.
This connector comes at two part numbers, and both have mount points along wider push keys.
LT-636 this is 3 In, 6 Out
LT-639 this is 3 In, 9 Out
For some time I was searching to find a better design of Mini Quick connect terminal, than what the German WAGO has in their product range.
WAGO came with the idea of inline (per wire connector), along Chinese manufacturing of separate plastic base with screw type mounting plate.
You are obligated to buy four parts for a single three wire connection. :P
Three connectors along a grey plastic support plate.
The Chinese (factory brand unknown), they came with a much better and practical idea, at the fraction of the costs.

I have a DIY project ahead, and I need a Mini Quick connect terminal, so to mount it externally over my Breakout Box with EU Receptacle for my AC Bench top Power Meter.
LT-636 (3 In, 6 Out), this seems as ideal to me.
I can connect to it anything this has insulated wires, and the spacing between the exposed wires (wire length) this is irrelevant, because LT-636 this has many output ports.
Are LT-636 levers much easier to use than older design of PCT212 and similar?
I will discover that in two weeks time.
SUNSKY e-shop has them at unbeatable price, and I got two of the for a test. ;)
---------------------------------------------------------------------------------------------
Past week I did send an email to WAGO, my question was of how many times they levers can be reused?
Did they run any tests?
Neither WAGO headquarters and neither their Greek WAGO distributor he was able to deliver an answer. :P

Looking forwards to read your impression about these LT-636.
Nice find ! ;)

I ordered two of them as samples for inspection.
The one came damaged, due manufacturing error.
Inside there is a common metal clip for its one colored row (output).
The Blue row is damaged, the plastic levers, they are unable to control the inner metal cage.
The good working one, this makes a loud clicking sound when its lever this is released.
The output clips they do hold thin wire:
0.30 mm (copper)
2.5 mm solid copper
2.0 mm stranded copper
2.5 mm stranded plated copper (due the increased hardness per strand).
The input clips:
They accept as Max of 3.0 mm solid copper
2.5 mm stranded copper
Metal cages issue about highest supported wire diameter, with a bit of assistance from a drill bit (end side), you may unblock the path fully.
If the clip this is not accurately shaped, from the factory.
About supported wire insulation diameter.
Input side: 4.79 mm diameter
Output side: 4.40 mm diameter
Depth which host the insulation 3.6 mm at both (input / output) ends.
The factory specification of 8 mm wire support, over the housing this is inaccurate and false advertising. :P
On paper specification 6mm as Max, again false advertising, you have to strangle for such a tight fit.
If you succeed using 2.5 mm solid copper at both ends, then 35A as max this is possible.
The damage part, this is still usable but for DC applications only, as I can still use the RED and Yellow rows. :)

I think that the poor quality control in the factory, this killed the enthusiasm.
Too bad for them.
Lesser supported wire diameter than the advertised? They are scammers.
