1.Application
GSG3-125 series isolator is used, as master switch of power supply in power distribution network, to break or close the circuit with load. In on-state, Isolator can allow normal current and also failure current within the stipulated time to pass through. In off state, Isolator can isolate electrical equipment and circuit with power supply due to its reliable insulation gap, and so can prevent electrical equipment from over voltage.
