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

    Another point, my lathe VSD (single-phase in 3 phase out, 4kW) does not trip a type AC ever, neither does the 3kW SP motor on my compressor on 99% of the switch on's. It does on the odd occasion which is a B nuisance, but I am not particularly inconvenienced so not worth a soft starter.

    Note that the inverter is wired to start with no load, and then the motor is started with a normal control signal to the inverter which slowly accelerates the motor. It should not be used any other way, although it can act in a soft start manner on power up with some other settings.
