New wylex mini RCBO

Former Community Member

I can’t help but notice how small these are, but where has the earth tag gone? How do these devices detect earth?

I’ve notice a tiny metallic strip on the back and front of the breaker but the one on the back doesn’t make any contact with the board as the din rail in wylex boards actually have a groove.


I know someone will have the answer out there.

    Actually I was referring specifically to the new Wylex AFDD/RCD/MCB combi offerings. It seems that they invoke 'sympathetic trips' on adjacent devices when the device connected to a faulty circuit trips out on what is identified as a trip of the RCD element.
