Asymmetry Relay
MK 9040N

The MK 9040N asymmetry relay of the VARIMETER series monitors asymmetry, reverse voltages, phase failure as well as incorrect phase sequence in three-phase networks. Early detection of impending failures and preventive maintenance prevent costly damage and as a user you benefit from the operational reliability and high availability of your system.
