RCD Type B ????
RCD Type B ????
(OP)
Hi
Can anybody tell me who manufactures a 'type B RCD', this is a type which is suitable for use on smooth DC. The type reference is not related to the tripping characteristic of a circuit breaker or combined circuit breaker / RCD.
Any help greatly appreciated.
Regards
Alan Edwards

I know that a type B does exist, any inverter / drive system manufacturer includes reference to them in their docs, unfortunately they don't seem to be able to point to a manufacturer.
My problem is futher complicated by the fact that I need a 100A RCD, any manufacturer who makes something that resembles a type B only goes to 63A

"You could check out the Bender RCD's, in particular the RCMA470LY / RCMA475LY.
http://www.bender.org/prod.html
I installed one of these (the RCMA472LY) the other day and it is advanced but also very expensive. It can be set as low as 30mA. I don't remember the upper limit, but you'll find the manual on Bender's website. You will need an external contactor (or suitable MCCB) and a current transformer."
