CROUZET CONTROL

3 phase, phase control MWS, MWS2

Control relay for 3-phase network that monitors the phase sequence for phases L1, L2 and L3 and checks whether one or more phases are lacking. As long as the phase sequence and voltages are correct (>183 V AC), the output relay(s) is closed and the yellow LED (LED indication) is on. If a phase sequence or phase interruption fault occurs, the relay drops out and the LED turns off. Does not measure returned voltage.
