I take a look inside a residual current circuit breaker (RCCB), also known as a residual current device (RCD). This super cheap clearance item came from Screwfix.

The permanent magnet holds the trip lock in the on position until a fault current weakens the flow through the relay, causing it to drop out.
These RCDs are completely sufficient for household applications, since the direct current problem does not exist there.
In the USA, we have devices that have their controls passed on the house wiring. I have never owned such, so I don't know what they might be. If this safety switch doesn't like DC, it would seem that these devices could defeat the switch. Maybe that is why your switch model is being discontinued…
Interesting find….cheers.
Clearance probably because the regulations have changed again 🤣
Change all the time!
Green = OFF and Red = ON is very common with disconnector switches in medium and high voltage. It is meant as green = safe to touch (after grounding); red = gtfo
Why not showing the toroid? It would be interesting to see if the current of the sensing winding is sent directly to the solenoid or instead "processed" somehow by some other components…
if you ever want to know the flag colours, red = dead, green = safe, same with traffic lights and guns… but you usually only get a red dot on guns
I only use outdated non-compliant parts for like testing/experimenting stuff (but then not as an rcd but as simple 63A switch)
This breaker is an AC type and essentially obsolete. New installations now need type A which can handle a DC component in the load, you can now only use type AC where there is no possibility of DC components on the load.
I wonder if there's more than £1.53 in the silver contacts. Probably not. But close.
Thanks for that Julian, my local Screwfix had one in stock, at thirty bob it would be rude not to.
it's the difference between what you get if you hold the live and then touch either the earth or the neutral. Do the earth test first as doing the neutral first you will not live long enought to do the other test.🙂
