Medium Voltage Circuit Breaker 17.5 kV

Medium Voltage Circuit Breaker 17.5 kV

HVEX medium voltage circuit breakers are essential for the control and protection of electrical systems. They utilize vacuum interrupters to extinguish electrical arcs and are equipped with spring and solenoid-operated mechanisms for opening and closing, which can be operated manually or automatically. With state indicators and auxiliary connectors for integration with control and protection systems, they ensure safety and efficiency. During anomalies, they isolate the source from the load to protect the system. Compact and reliable, they are ideal for substations, ensuring the continuity and safety of electrical operations.
