Switches and Disconnectors

for Grid Protection

Grid protection ensures swift response to abnormal operating conditions like faults, voltage or frequency fluctuations in the interconnection of the main power grid with secondary distribution systems or renewable energy plants.

Microelettrica offers solutions for different poles configuration and current values, to cover a wide range of needs and provide effective faulty sections isolation, increasing power systems reliability and safety.
