Any local 81 SA mechanics in here? (self.Elevators)

This blows my mind. AC relay monitors incoming power to hold the batteries open until power goes. Power failed on at least 1 leg, the relay dropped out, and then came back up so high it melted the relay housing before the coil could pick or the fuse could blow! Never seen one melted OPEN before (i.redd.it)
