	The DNW... type three-phase mains monitor is used for the comprehensive monitoring of a three-wire or four-wire mains for phase failure, neutral conductor break, overshooting or undershooting of the three phase voltages, unbalance of the three phase voltages and the phase sequence (rotating field). An auxiliary supply is not required.
