Description

The asymmetry relay BA 9040 of the VARIMETER series monitors asymmetry, reverse voltages, phase failure and incorrect phase sequence in three-phase networks. The 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.
