Product description

The Phase monitor MH 9352/001 of the VARIMETER series monitors over and undervoltage, voltage failure as well as wrong phase sequence at three-phase networks. 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.
