Protection Relays

for Loads/Motor Protection

Motor protection and control ensures the continuous functioning of the power AC motor. In cause of a fault, damage to the electrical motor is prevented thanks to the constant monitoring of the state of its parts, from starting sequence to rotor block, to avoiding it could work as a generator.

Microelettrica solutions for Motor protection are suitable to meet different needs, including voltage and power control for medium and large size induction motor as well as single specific protections.
