The Reletek three-phase DIN-rail voltage monitor monitors the mains voltage and detects overvoltage, undervoltage, phase loss, phase sequence faults and phase imbalance. It operates with a supply voltage of 208–480 VAC and has a time delay of 0.1 to 10 s.

  • Type: Three-phase
  • Mounting: DIN rail
  • Protection: Overvoltage, undervoltage, phase loss, phase sequence...

  • 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.

    Undervoltage

    Protects against dangerous voltage drops (e.g. < 190V). It is essential for devices with motors and compressors (air conditioners, refrigerators, pumps), which overheat and are damaged when they try to operate at low voltage.
