Hello all -
I got climate-controlled room with a lot of expensive computer equipment generating a lot of heat, and I need to build an emergency shutdown circuit if the temperate rises above a certain set-point.
I'm thinking of using a shunt-trip circuit breaker to cut power to the computers and chiller when a temperate controller closes a connection at the set point temperate. This would power a magnetic coil in the circuit breaker thereby tripping it.
Now to my question: I don't really like the idea of continuing to power the coil after the breaker is tripped and the room starts to cool down. Would this burn-out the coil? Is it even necessary anymore?
My idea is to power the temperature controller from the same circuit as the computer equipment & chiller. So, when the set-point is reached, the controller would power the shunt-trip coil, tripping the beaker, shutting down itself along with the computers and chiller.
Will this work?
