DOLD 0033572: AK9840.82 3AC50/60HZ 660V Asymmetry Relay
The asymmetry relais AK 9840 of the VARIMETER series monitors voltage asymmetry, under voltage, phase failure as well as incorrect phase sequence at three-phase mains. The measurement is very simple and can be carried out without much wiring effort, as no separate auxiliary voltage is required. Early detection of impending failtures and preventive maintenance prevent costly damage and as a user you benefit from the operational safety and high availability of your system.
