content: Hi all,I am building a three phase 400V 16A machine controller cabinet and I find the normal CEE chassis part ( IEC 60309) rediculous in size to use.For my single phase cabinets I used the Neutrik PowerCon connectors but they don't seem to have a three phase version of that or do theyI found a Wieland GST18/5 connectors but they are for in the ceiling where nothing touches.So has anybody a viable alternative for the CEE connector ?Thanks

content: Basically it depends on the following factors:- How (de facto) standards-compatible you want to stay- How easy parts in case of a defect can be organized- how easy a safety check due to work safety regulations can be done (appliance tester has to be adapted to that circuit)- most important: Which Power has to be transmitted?In most cases, CEE plugs are the best compromise between all this considerations.Alternatives:https://en.wikipedia.org/wiki/PerilexHartingLAPP Epic

content: The CEE connectors are indeed very bulky, but I know of no others that conform to codes.Perhaps you could consider a permanent connection instead (like a domestic stove/oven)? If it's an industrial installation, you'll need certified electricians there anyway.

content: Quote from: nightfire on January 10, 2021, 10:42:10 pmAll very good pointsBecause this is for my own home milling machine I do not have to obey standards although I do as much as possible for safety and emc follow the machine guidelines.The problem I had is that I don't want a fixed attached cable so I can easily work on the cabinet when needed.Thanks for the alternatives, I forgot all about the Harting connectors, they will suit my purposes

content: Bonjour Monsieur Kjelt:American brand Hubbell has 480V and 600V twist lock connectors,https://www.hubbell.com/hubbell/en/Products/Electrical-Electronic/Wiring-Devices/Locking-Devices/Insulgrip-Twist-Lock/HBL2731/p/1640171See HBL2731S, 2741S.I have seen similar in Paris, NOT CE rated.In a home install, you should consider transient protection.Bon chance,Jon

content: Quote from: Kjelt on January 10, 2021, 10:18:03 pmSwiss SEVtype 25 sockets would fit the bill, assuming it's for indoor use. It's slightlysmallerthan a Schuko, but is 3 phase, 16A. (The horizontal pin spacing is the same as on a Europlug.)

content: Quote from: bingo600 on January 11, 2021, 03:08:13 pmYes we have them too, thanks for mentioning them, but the footprint of the chassispart almost equals the CEE and is way less sturdy.

I just checked, and panel-mount Type 25 sockets go into a 43mm diameter hole.socket:https://online-katalog.feller.ch/kat_details.php?fnr=8725.P.61just the part that goes through the hole, but with drill size:https://online-katalog.feller.ch/kat_details.php?fnr=920-8725.P.61

content: Quote from: tooki on January 11, 2021, 05:11:41 pmYes looks like you are right.I just realized another important requirementBecause the chassispart is on the machinecabinet it MUST be male since the plug might carry mains voltage so there should be no way to touch that so the plug MUST be female.

content: Quote from: Alti on January 11, 2021, 09:04:40 pmYes it is not a 2000kg Haas but a small machine, main spindle servo is 400V 3kW but will probably use not even half and the rest is less than 400W so not going for the entire 16A.
