ZW32-12/630-20 Outdoor High-voltage AC Vacuum Circuit Breaker (Electromagnetic Type) can be configured with current transformers and voltage transformers to meet primary and secondary fusion requirements. It can be paired with different models of intelligent controllers to function as an automatic recloser, sectionalizer, or intelligent boundary circuit breaker, achieving distribution network automation.

Main Functions

• Equipped with electromagnetic current transformers to achieve phase current and zero-sequence current measurement and protection functions.
• Equipped with electronic voltage transformers to achieve zero-sequence voltage measurement and protection functions.
• Paired with independently installed dual-winding PT to achieve power supply to the terminal and line voltage measurement functions.
• Used as a sectional or tie switch to monitor line voltages on both sides of the switch, supporting local feeder automation.
• Can be combined with controllers to achieve intelligent automation, such as recloser, sectionalizer, and boundary circuit breaker.
• Optional three-phase linkage isolating switch with anti-misoperation interlocking, facilitating operation and maintenance.
• Miniaturized spring operating mechanism, low energy consumption, direct-acting transmission, simple structure.
