Hi,

Need to have emergency stop switches for a workshop that will kill all the power

Looking for a remote control MCB or similar that can be added to distribution panel to enable a complete mains ring to be isolated from one or more push buttons around the workshop

I am unable to find such a solution online

Any ideas?

Thanks
 
Might be better using the contactor in the feed to the ring - this would avoid all the lights going out. Daz
 
A plain and simple contactor is all you need on the Ring final circuit after the MCB /RCBO plus EM stop buttons.

Is the EM stop circuit for convenience or to comply with a Reg?
 
Sorry have to say kill the supply, let the EM lights take over until it's sorted, see the point of only killing the sockets, but Nah take it all out of the equation imo.
 
123 has it right. Kill the machines, not the lighting. Need to see things when somethings gone t*ts up. Daz.

To remotely trip an mcb you need to add a tripping auxiliary to the mcb, either a shunt trip or an under voltage release depending on your act requirements.
At first glance I would have thought an under voltage release would be more suited to an emergency switching setup than a shunt trip.
But I think you need to take a step or two backwards and establish the details of exactly what you need, which could include risk assessments and a lot of research into statutory legislation.
