Product Description

ZW8-12/630-20 high Voltage High Voltage Outdoor Vacuum AC Circuit Breaker


The circuit breaker is mainly used in motors and Transformers with large capacity and substations with frequent breakdowns. The load switch can break the normal load current and has certain arc extinguishing ability. The isolation switch does not have any breakability and can only be broken without any load current. It acts as an electrical isolation device. The circuit breaker has the function of breaking the accident load, and with all kinds of relay protection, plays the role of protecting electrical equipment or circuit. The isolation switch is a switch that meets the isolation requirement at the disconnecting position. The load switch is a switch that can break the normal load current. A circuit breaker is a protective appliance with overload, short circuit and undervoltage protection.
