No apparent way in!

Moulded brown plastic with 3 terminals.



How come contacts welded with a 30ma rcd installed & working?



Well 30mA is (roughly) the minimum that will trip a RCD, the RCD does not

limit the current to 30mA in the event of a direct short. There was
probably

6000A flowing when the RCD and MCB tripped.



Anything in here to help you?

mmm lots of minutely different variations of Platinum Flat plate yokes and
switches.... none of which appear to be what I have here :(

No number on the one you have?
