  • Protection Type

    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.

    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.
