Suitable relays for 3 phase Advanced Kit

Hi everyone,


I've just received my Advanced Kit, which I want to use as a 3 phase charger.  I've been looking over data sheets for 4 pole 40A contactors that are available in my country (Australia), and am coming up short of anything that would appear to fit in the OpenEVSE enclosure.


I'm wondering what 4 pole contactors others have used to make their charger 3 phase?  Can anyone offer a link or make/model details for suitable contactors?  Of course it'd be great if I could buy something locally, but if I have to source from somewhere outside Australia, I'd like to be sure I'm ordering something that will fit/work.


Thanks in advance,

Dave.

Hope it's ok to bump questions.  I'm really hoping someone can give me a tip on what relay/contactor to buy.

OpenEVSE has not found a 4 pole relay that fits in our enclosure. Everything we have tried is too tall. 


If a part is identified, we would certainly offer the part for sale as well as a 3 phase kit.

Hi Dave, did you ever find a suitable relay for a 3-phase install into the Advanced Kit? I'm keen on buying an OpenEVSE but need 3-phase charging.

 Another one late to the party ... I'm looking to use a DIN rail mounted Finder 4 pole 63A contactor, so a new enclosure is required.

Hi All, I'm in Australia and I installed a Hagar ESC440 in mine today, just fits under the cover nicely.

Nice, did you make a new harness, or just modify the provided one ?

Thanks for updating my post, Tom. That's great to know that there's a suitable relay.

I haven't got around to it yet but I'm planning just to modify the supplied harness. I'm using 6mm2 4C+E flex as my supply cable, hoping I can fit the harness wire and the 6mm2 into a pin lug together.

The new Finder 4 pole 63A contactor arrived today, and I'm pleased to report that it fits within the existing enclosure. A few small mods required:

- it is DIN rail mounted so a short length has been screwed to the backplate

- all wires are fastener via rising cage screw attachments so I've modified the wiring harness using crimped on ferrules rather than the push-on connectors.

Otherwise I'm looking forward to completing the build. I also ordered a L298N Stepper Motor Driver board to drive the lock/unlock motor on the type 2 socket I'm using.


The Finder part number is 22.64.0.230.4310. I ordered it from RS Components but places like TME also stock it.
Finder 22 Series Contactor, 240 V ac Coil, 4-Pole, 63 A
