Type Low Voltage Three Phase Isolator Switch , 630 Amp , Copper T3 , DMC V0 , With Embossed contact
HGL-630 series load disconnector, rated voltage of 660V, the maximum current of 400A, the shell material for the V0-class flame-retardant plastic
1. General power transmission operation: first disconnector, after the circuit breaker or load switch; isolation switch power operation: first disconnect the circuit breaker or load switch, and then disconnect the disconnector.
2. When used and other electrical equipment, its rated voltage, rated current, dynamic and stable current, thermal stability of the current must meet the needs of the occasion. The function of the disconnector is to disconnect the circuit without load current, so that the equipment and power supply has obvious disconnect point to ensure the safety of maintenance personnel, isolation switch does not have a special arc device can not cut off the load current and short circuit current, It is necessary to operate the disconnector in the circuit when the circuit breaker is disconnected from the circuit.
