    Single-phase voltage relay designed to protect household and commercial electrical devices from dangerous voltage fluctuations in the power grid. This compact device, mounted on a DIN rail, continuously monitors the network voltage and automatically disconnects the load when the voltage exceeds the set limits—thus protecting equipment from burnout or other damage. Once the voltage returns to a safe level, the load is reconnected after a preset delay.

    This model features a TrueRMS measurement system, thermal protection, a clearly visible red LED indicator, and can be integrated into both residential and professional electrical installations. 

  • Product description

    Technical Specifications:

    Voltage: 50–400 V AC (single-phase)
    Frequency: 45–65 Hz
    Rated load: 40 A
    Maximum load: 50 A
    Trip time (over-voltage): 0.02 s
    Trip time (under-voltage): up to 1 s (0.02 s if < 120 V)
    Load turn‑on delay: 5–600 s (default – 15 s)
    Voltage limit adjustment:
    • Lower: 120–200 V (default 170 V)
    • Upper: 210–270 V (default 250 V)
    Indicator: Red (G3R version)
    Display color: Red
    Temperature indicator: Yes (internal sensor)
    Thermal protection: Built‑in
    Mounting: DIN rail (2-module width)

    Functions:

    Continuous voltage monitoring using TrueRMS – more accurate measurement even with distorted waveforms

    Automatic load disconnection in case of dangerously high or low voltage

    Programmable settings – voltage limits and turn‑on delay

    Thermal protection against overheating and internal temperature monitoring

    Visual indication of operation and voltage status (red LED)

    Suitable for refrigerators, air conditioners, boilers, pumps, household systems, etc.

    Usage:

    Single-family homes, apartments, cottages

    Offices, commercial spaces

    Integration in electrical panels

    Protection for refrigerators, washers, TVs, AC units, pumps, servers

    Recommended where frequent grid voltage fluctuations or sudden power switches occur

    Advantages (+):

    Compact, quick installation on DIN rail

    Suitable for all standard single-phase household appliances

    Accurate TrueRMS measurement even with distorted voltage

    Adjustable turn‑on delay – safely start sensitive devices

    Integrated thermal protection ensures longer device life

    Visual operation indicator – clear and easy monitoring

    Disadvantages (–):

    Not designed for three-phase systems

    No Wi‑Fi or remote monitoring features

    A great choice for anyone looking to protect valuable electrical appliances from dangerous voltage fluctuations. Whether you're a professional installer, engineer, or responsible homeowner, this device ensures reliable protection, longevity, and clarity in operation — with programming options and additional thermal protection not present in earlier models.
