4 pin screw connectors on soldering stations and so on, what is their max current/vol

CuriousOne

tage?

I mean connectors like this:

(Seller marked them as XLR, which is wrong)

One seller, when asked, said that they are rated 220VAC/3 AMP maximum, but I'd like to get more solid source, if possible. Any info?

Looks more like a Cannon or Amphenol style connector. Can't find links right now.

Ya, their not XLR.

I think they are Hirose HS series. See:
http://www.hirose.co.jp/cataloge_hp/e10100020.pdf
This spec covers many variations.

This is the same connector as was used on older Ham and CB radio microphones.

I used to use them for power. It looks like they are capable of 7A or 10A.

Hope this helps.

Thank you very much for information.

As that datasheet rates, 1000V /7 A is per contact. So I assume, I can use it for AC power cable with loads up to 500VA? I want to replace bulky IEC cable with something more compact, and pull-out resistant.

TE Connectivity says 500VAC @ 5A:

So I assume, seller's proposed rating of 220VAC @ 3A is quite reliable

I don't think that spec says that.
The 500V or 1000V ratings are based on doing HiPot testing to asses the quality of the breakdown voltage of the insulation.
This does not mean you can run at that voltage.
I would not use the 500V breakdown part on anything greater than 120VAC.
The peak voltage is 120VAC * 1.414 = 170VDC. But don't forget the power line also has voltage spikes riding on top of this.
240VAC would require a minimum of 1000V breakdown parts.

I have them for Mic use on my underwater Comms system .

The plastic between is so massive that I would have no problem with it being used for 120V use.

The real issue is tracking and then arc over .

On the bottom of pate 18 on the PDF above it says to the effect .

the figure stated is the test voltage ..... recomended use is at 1/3 of the test voltage ..


now here is the bad side ......... the female contacts in the PLUG are not resessed very deep ( Mine are inset less then a few mm ..... so there is a shock hazard there ........ a " IEC 320" has a Like a .25 inch recess.

Seems like miniature, but capable connectors are rarity. I've got a bunch of these:

They aren't that small as they seen, and also have only 200Vamp rating.
