Product Features |
This circuit breaker is consisted of main body of switch, feeder terminal, power supply voltage transformer, sensor, connecting wires. The mainbody of switch, feeder terminal, power supply voltage transformer adopts Military level aviation connectors, connected by outdoor type fully insulated cables, the connectors meet the requirements of national standards. The current transformer(A/B/C/O) and zero sequence voltage sensor inside the switch mainbody, supply Ia，Ib，Ic,I0(protection and measurement, current signal and zero sequence voltage U0. The feeder terminals have the functions of single phase to earth, short circuit fault between phases, also it has the functions of distribution automation three remote control and fault recording. It is a ideal switch device which realizes “distribution automation” and has the capacity of opening&closing the load current, overload current and short circuit current. |
