Mechanical Protection vs RCD Requirements

The remote reset looks a neat solution to the problem.
But unless I’ve misread something it needs a control transformer as the closing operates at 12 to 30V.

There's a few out there Tony, Legrand do one, and I was fairly certain that ABB did an all in one device, rather than an add on module.
Thes add ons, aparently work with MCBs as well as RCDs?

I suppose it makes sense to use LV. It’s OK the supply being knocked off and then having 230V running through the protected area to reset it.

Thanks loads guys - these auto-on and auto-reclosers are a great idea! Solves the problem. Cheers. SW
