Neutral Monitor
SL 9069
The IL/SL9069 neutral monitors in the VARIMETER series monitor the neutral conductor in electrical systems and three-phase networks. Monitoring is simple and does not require a great deal of wiring, as no auxiliary voltage is required. The detection of a missing neutral conductor, a phase or a reversal of the neutral conductor with a phase prevents costly damage and as a user you benefit from the operational safety and high availability of your system.
