  • Product description

    Modular three-phase electricity meter | CT-connected …/5 A | 1.5(6) A | 3×230/400 V | 1 tariff | pulse output | IP20 | DIN | THORGEON 01004

    THORGEON 01004 is a modular three-phase four-wire meter designed to be connected via current transformers (CTs) with a 5 A secondary. Rated measuring current is 1.5 A and maximum 6 A, so the metering limit is set by the chosen CTs, not by the meter itself.

    Key point:
    When an incomer or feeder is 150, 250 or 400 A, a direct-connected meter will not do. Together with …/5 A current transformers the 01004 records active energy on such lines while taking only 4 DIN modules. It is a solution for internal metering – the manufacturer does not state MID.

    Bidirectional metering
    The manufacturer does not state that the meter records imported and exported energy separately. If energy exported to the grid must be metered separately via CTs, choose a bidirectional model, e.g. the Eastron SDM630MCT-2T with MID.

    Communication interfaces and integration

    Electrical pulse output (400 imp/kWh)
    Pulses are passed to a PLC, BMS or data logger; note that pulses relate to the CT secondary side, so the CT ratio must be applied in the system.
    Local LCD display
    Readings are taken at the board; there is no RS485, M-Bus or Wi-Fi interface.

    How it works

    The meter mounts on a DIN rail; phase voltages and neutral are connected directly, while the current circuits go through three current transformers with a 5 A secondary.

    The meter measures the CT secondary current (rated 1.5 A, max. 6 A) and records active energy on all three phases.

    Actual consumption is obtained by multiplying the LCD reading by the CT ratio in use (e.g. 200/5 A = ×40), unless the manual allows the ratio to be entered into the meter.

    Why choose the THORGEON 01004?
    It is a compact and economical way to meter high-current three-phase lines: the current limit depends on the CTs, so the same meter fits a 100 A feeder as well as an incomer of several hundred amps.

    Main functions

    • CT connection …/5 A – metering on lines above 100 A
    • Active energy metering – kWh reading on the LCD
    • 400 imp/kWh pulse output – signal to PLC or BMS
    • Four-wire scheme – 3 phases and neutral
    • Built-in battery – part of the manufacturer's design
    • 4-module housing – takes little space in the board

    How does it differ from similar models?

    THORGEON 01003 Direct connection up to 100 A; the 01004 is for higher currents via CTs.
    Eastron SDM630MCT-2T Via 1/5 A CTs, 2 tariffs, RS485 Modbus, MID and multifunction measurement; the 01004 is plain kWh metering without MID.
    Eastron SDM630MCT-ML-1 Via CTs, RS485 Modbus, MID; the 01004 has no digital interface.
    Eastron SMART X96-1 96×96 mm panel instrument via CTs with Modbus and MID; the 01004 is a modular DIN meter.

    Where is it used?

    • Company incomers 125–400 A
    • Production halls and compressor rooms
    • High-power tenant feeders in shopping centres
    • Boiler rooms and heat substations
    • Grain dryers and farm incomers
    • Upgrading existing CT schemes instead of induction meters

    Use by need

    Electricians.
    A simple CT meter for high-current lines, 4 DIN modules.
    Energy managers.
    Internal kWh metering of large consumers without an expensive analyser.
    Automation integrators.
    400 imp/kWh signal scaled by the CT ratio.

    Practical use

    If a production hall has a 250 A incomer and you want its monthly consumption, fit three 250/5 A current transformers and a THORGEON 01004 – multiply the LCD reading by 50 (if the ratio is not entered in the meter) to get actual kWh.

    Pros

    • Suits high-current lines via …/5 A CTs
    • Compact 4-module housing
    • 400 imp/kWh pulse output
    • Simple to use
    • 24-month manufacturer warranty

    Cons / limitations

    • No MID – for billing choose Eastron SDM630MCT-2T or SDM630MCT-ML-1
    • No RS485 / Wi-Fi interface
    • Current transformers must be purchased separately
    • The manufacturer does not state whether the CT ratio can be entered – manual scaling may be needed
    • Bidirectional metering not stated by the manufacturer

    Safety and installation notes

    • Installation by a qualified electrician only, with the supply disconnected
    • Never open a CT secondary circuit under load – short it first (dangerous voltage)
    • Observe CT orientation (P1/P2, S1/S2) and phase correspondence with the voltage circuits
    • Protect the voltage circuits with fuses or circuit breakers
    • IP20 – install only in a closed enclosure in a dry room

    Quick selection guide

    Via CT …/5 A
    1.5(6) A
    1 tariff, no MID
    400 imp/kWh
    A good fit when you need:
    • Internal metering on lines above 100 A
    • A compact CT meter in a DIN board
    • A pulse signal to automation
    Check before use:
    • That the CT secondary is 5 A and the accuracy class is suitable
    • That MID is not required
    • How the CT ratio will be applied to readings
    Important reminder: The meter works only with current transformers – it must not be connected directly into the power circuit; it also does not replace the operator's billing meter.

    How many pulses per kWh?
    400 imp/kWh on the secondary side.
    What is the warranty?
