Type B rcd availability

Baldyhugh

Hi

would anyone know of a supplier where I could get my hands on a 100A 100ma type B double pole rcd? I need one to supply three variable speed inverters. I’ve done the usual google searches but can only find 30ma ones and only rated up to 63A. 
 

Thanks in advance

    could you consider  

    a slow trip (s-type) first to ride the inrush, if that is what it is causing the trips. 

    Or filters if it is an HF / spikes issue. 

    Or filters wired a kind of ‘open delta’ if earth “leakage ” from RFI filters is the issue. (so we put filter caps L-L-L and L-N,  but not large ones L-E. We then have a larger one NE)  Can sometimes be done after the fact by ‘neutralling’  the earth terminal of a traditional potted filter, putting it in a plastic box and taking the CPC around it.

    Mike.
