    Shelly Pro 3EM-400

    €281.67 excl tax
    The Shelly Pro 3EM-400 is a three-phase energy meter that can be mounted on a DIN rail. It uses current transformers (with open core) to measure the energy in three individual phases, with currents up to 400A and with 99% accuracy.

    CHARACTERISTICS:

    ● Mountable on DIN rail;
    ● Performs three-phase measurements;
    ● Includes 3 current transformers;
    ● Measurement error less than 1% at 2-120A;
    ● Measures consumed and generated energy;
    ● Distinguishes between capacitive, inductive, and resistive loads;
    ● Informs about incorrect installations (phase sequence);
    ● Supports Modbus TCP;
    ● Persistent data storage with 1-minute resolution;
    ● Stores at least 60 days of data in the history;
    ● Can be used for both single-phase and three-phase installations;
    ● Can control other Shelly devices locally or through the cloud;
    ● Allows for the use of home and SMB scenarios.
    ● Excellent solution for homes with energy production, EV charging with power management, consumption based on energy price, decentralized decision-making and control of production and storage, etc.
