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

    The three inverters are all in the one db which is fed via a sub main from the incoming position about 59 metres away. I need rcd protection for the sub main aswell as the inverters so intend to put the type b rcd at the incoming position to cover everything. The inverter spec insists on type b as there is a dc element to them which will trip all other rcd types
