  • 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.

Description

Description

Single position voltage monitor with one contact, phase fault, overvoltage and undervoltage, independent upper and lower limit adjustment, neutral isolation for 3x400V. Controlled voltage range 170-220V and powered by the network.

For overvoltage and undervoltage control by adjusting beyond time both overvoltage and undervoltage independently and accurately. LED indicators for operation and fault indication. In case of a voltage drop up to 60%, it automatically cuts off even if we have not selected it.

    without having a low voltage as much as the limit I have set, it disconnects the circuit. I will do some more measurements and I will get back.
