Monitor for 3-phase, Phase Asymmetry, Phase Sequence, Over- and Undervoltage
Relays for 3-phase networks type PSSW1 monitor 3-phase networks for phase-sequence, asymmetry and over- and undervoltage.
Applications
Monitoring of 3-phase-networks at heat pumps, compressors or at machines at building sites.
Functions
