3 Phase Control Relay

[udud22]

Hi, I am new to HV Electrical Stuff. I am trying to use a emergency stop button to kill power to BOX A remotely.

The wall socket has 3 phase 380V supply without neutral. I want to introduce a control relay between BOX A and Wall socket. The remotely operated cable (20 metres) with Emergency stop button is connected as control input (0-24VDC) to relay. When the emergency stop button is pressed remotely, the control relay in-turn kills power to BOX A. Also planning to use a trip switch for manual intervention to turn the power back on again.
I am not sure what type of relays to use and how to wire them up. Is just relay sufficient and trip switch sufficient or does it need anything else ?

Hi and welcome. Your mention of emergency stop buttons suggests this is a safety critical control function. It is important to use the correct components and installation methods to achieve safety, and I think this is slightly beyond what we can advise on the forum given your unfamiliarity with control systems. I also note that your avatar flag shows you to be in the UK, although you describe your location as India. There may be significant differences in accepted practice for this type of work between the two countries.

I would suggest seeking advice from an experienced electrician who is familiar with local regulations for machine controls.
