Protection Relays (4)

The MRM4 provides all necessary functions to protect low and medium voltage motors at all power levels. The protection functions are based on current measurement. They supervise the motor start sequence (motor start), they detect a stall or locked rotor condition and they monitor the thermal condition of the motor.

The MRMV4 provides all necessary functions to protect low and medium voltage motors at all power levels.
