What is the simplest way to wire an emergency stop button so it stops the power to an MCB rated at 160A powering a building?

You would need to replace the 160A MCB with a 160A MCCB having 'under-voltage release' feature.

The e-stop push button switch NC contact, wired in series with the 'under-voltage release' coil, would make it failsafe.
