Hager H125D MCCB - What board/ Main Switch???

[cllelectrical]

I need to find a main switch to fit an MCCB board. There is no writing or stickers on the board.
All I know it that the breakers in it are Hager H125Ds

Can anyone shine any light on this?
Thanks

too little info. and a photo would help.

As above but possibly one of these?

I will get a photo tomorrow.
Its not the one on that link though, its bigger than that. Its an MCCB board, so main switch will be at least 125Amps I think.
Thanks for your help.

It'll be along the lines of one of these,

...maybe with adjustable 100A to 125A...

When a current rating forms part of an MCCB model/type number, it will be what is known as a ''Frame'' size''!!

Hager panel I've just put in had a 250 incommer

Yep, Main incomer breaker doesn't necessarily need to follow the same frame size constrictions, as the outgoing breakers.

Thank you. It is the main switch I need though, as there are just bars bolted in there at the moment.

Then you'll need to assess what the maximum load is on that MCCB panel and provide a suitable sized Main MCCB breaker.... That or a suitably sized isolator switch, (depending on the upstream protection being provided)

It will be a 125Amp isolator switch that I need

It will be a 125Amp isolator switch that I need

If you are sure that is the size of the 3 or 4 pole isolator you require, then visit the Hager website to locate model number and details etc....

Thank you. I called Hager's technical helpline! Don't know why I didn't think of that sooner!
In case anyone is interested, or searches for this in the future, the model numbers were:
Board - GN208P
250A Isolator - GN323S
