Switches and Disconnectors

for Loads/Motor Protection

Motor protection and control ensure the service continuity of the power AC motor. In cause of fault, damage to the electrical motor is prevented thanks to constant monitoring of its parts.

Microelettrica provides solutions for different poles configuration and current values, to cover a wide range of needs and safeguard your equipment effectively, extending its life and increasing power systems reliability.
