Zw20 High Voltage Vacuum Breaker with Intelligent Controller

General:
ZW20-12 series outdoor AC vacuum circuit breaker is 12kV distribution equipment of 3 phase,50Hz. It is used to connection and break load current, over-load current and short-circuit current. It is applicable in occasions with frequent operation and automatic power distribution network. It adopts vacuum arc-extinguish mode and SF6 gas insulation. The cabinet employs gas seal, explosion proof and insulation structure technologies. It has excellent integral seal performance. The spring operating mechanism adopt mini design. Action reliability is higher than the traditional spring operating mechanism. It accords with the standards of IEC62271-100.
