ATCA Power Switch

This project is a set of 3 boxes which together provide emergency over-temperature shutdown for the ATCA shelves in PRB. Two boxes contain respectively 2 and 3 solid state relays for the two-phase and 3-phase power to the shelves. The third box contains a latching relay with a thermostat, indicators and buttons.
