July 2004 Moulded Case Circuit Breakers 7 16 – 2500 Amperes for IEC Applications Series G Frame Sizes GE through GL dc Switching Duty The GE- to GL-Frame circuit breakers are also suitable for switching dc currents. The GN- and GR-Frame circuit breakers are not suitable for dc currents due to the solid-state overcurrent release system. For switching dc currents, however, the maximum permissible dc voltage per conducting path has to be considered. For voltages higher than 250 volts, the series connection of two or three conducting paths is required. As the current has to flow through all...
