Ammeter (moving iron) with switch
Wiring Diagram
range moving iron Ammeters with integral phase selection switch 96mm square format supplies operating from current transformers with secondaries. Specify current transformer primary scale when ordering.
Application EC72/96 Ammeter with integral manual changeover switch specifically designed measure currents each phase three phase system. switch design ensures that secondaries current transformers shorted during changeover overvoltage produced eliminated. switch four positions Phase (L1) Phase (L2) Phase (L3). scale degrees with times overscale zeroing adjustment.
