Medium Voltage Vaccum Circuit Breaker (VCB) 17.5 kV

HVEX medium voltage circuit breakers are the perfect choice for ensuring protection, control, and efficient switching of electrical power systems in industrial substations, utilities, and critical installations. Developed with cutting-edge technology, they use vacuum interrupters to guarantee fast and safe arc extinction, providing high operational reliability. Equipped with spring- and solenoid-operated mechanisms, HVEX circuit breakers can be operated manually or automatically, facilitating seamless integration with modern automation, control, and protection systems. State indicators and auxiliary connectors ensure full connectivity with protection relays and SCADA systems, delivering maximum safety, quick switching operations, and continuous system monitoring. During faults or overloads, HVEX circuit breakers instantly isolate the load from the source, preserving electrical system integrity and preventing damage to connected equipment.
