The 03.031.0155 three-phase voltage monitor is DIN-rail mounted and measures overcurrent and undervoltage via a current transformer. It supports connection to a single-phase 2-wire system, a three-phase 3-wire system, or a three-phase 4-wire system.

  • Type: Three-phase
  • Mounting: DIN rail
  • Protection: Against overcurrent and phase sequence faults
  • Measurement:...

  • Protection Type

    Phase Sequence

    Ensures that the phases are connected in the correct sequence (L1, L2, L3). Prevents three-phase motors and pumps from rotating in reverse, avoiding serious mechanical damage.

    Overvoltage

    Monitors current consumption in Amperes (A). If the connected devices draw more current than the safety limit, the monitor cuts off the supply to prevent overheating of the cables and the risk of fire.
