    ESTXM302 – a modular three-phase energy meter, direct connection 3x10(100) A, DIN rail mounted and designed for 3×230/400 V (or 3x220/380 V) networks. It shows consumption on a digital, backlit LCD display, so readings are clearly visible even in a poorly lit panel. Used for check metering in manufacturing, storage and office premises, and in distribution boards where the consumption of a specific branch circuit needs to be known.

  • Product description

    Modular three-phase energy meter | 100 A | 3×230/400 V AC | DIN | ESTXM302

    ESTXM302 – a modular three-phase energy meter, direct connection 3x10(100) A, DIN rail mounted and designed for 3×230/400 V (or 3x220/380 V) networks. It shows consumption on a digital, backlit LCD display, so readings are clearly visible even in a poorly lit panel. Used for check metering in manufacturing, storage and office premises, and in distribution boards where the consumption of a specific branch circuit needs to be known.

    Key idea:
    Check metering doesn't need communication modules or apps – it needs an accurate reading that can be read in a second. The ESTXM302 is exactly that: direct connection up to 100 A without current transformers, a backlit LCD and a metal-and-ABS enclosure rated for -10…+65 °C. It suits situations where the electrician just wants to install it, close the panel and forget about it, while the owner notes the reading once a month.

    How it works

    The meter is connected in series into the three-phase line after the circuit breaker: L1, L2, L3 and N to the input terminals, the load to the output. The marking 3x10(100) A means the basic current is 10 A and the maximum is 100 A, with the entire current flowing through the internal measuring elements, so no current transformers are needed. Active power is calculated from the voltage and current of each phase, then integrated over time and accumulated as consumed energy in kWh.

    Readings are shown on a digital, backlit LCD display – consumption is read straight from the panel, with no extra instruments. The meter works on both 3x220/380 V and 3×230/400 V networks, at 50–60 Hz, and requires no configuration at all.

    What makes the ESTXM302 worthwhile?
    It provides accurate check metering wherever a mains meter is absent or doesn't split consumption by branch circuit, without burdening the installer with either current transformers or communication settings. The metal-and-ABS enclosure and wide temperature range also allow mounting in warm production cabinets.

    Key features

    • Active energy measurement – consumption accumulation in a three-phase system up to 100 A.
    • Direct connection – no current transformers, quick to install.
    • Backlit LCD – readings clear even in a dark panel.
    • One total register – a single kWh reading for check metering and cost allocation.
    • Two voltage standards – 3x220/380 V and 3×230/400 V networks, no switching needed.
    • Durable enclosure – metal and ABS, operating temperature -10…+65 °C.

    Where is it used?

    • Branch circuits of manufacturing workshops and equipment groups up to 100 A
    • Check metering in warehouses and logistics premises
    • Tenant consumption in offices and retail premises
    • Distribution boards, where individual lines need to be measured
    • Electrical installation checks and consumption measurement in three-phase systems
    • Branch circuits for heat pumps, compressors and refrigeration equipment
    • Three-phase supplies for farms and workshops

    Use by need

    For the domestic user.
    If the house has a three-phase supply and you want to see separately how much a heat pump, a workshop or a rented part of the property consumes, the ESTXM302 is fitted into that branch circuit's panel – a reading on a backlit display, with no apps and no internet.
    For businesses and industry.
    The meter lets costs be allocated by workshop or tenant and lets equipment consumption be compared month after month. The metal-and-ABS enclosure and the +65 °C limit suit warm production cabinets.
    For electricians / engineers.
    Direct connection up to 100 A – a circuit breaker matched to the conductor is required ahead of the meter; current transformers are not needed. Observe the phase order and terminal marking, and always connect the neutral. If the site requires billing metering, check the MID certificate in the manufacturer datasheet – it is not stated in the source.

    Practical example

    In a rented 200 m² warehouse with a 3x63 A supply, the landlord wants accurate consumption metering without extra systems. An ESTXM302 is fitted after the incoming breaker; the reading is 1,240.3 kWh at the start of the month and 2,118.7 kWh at the end, so the tenant is invoiced for 878.4 kWh at the tenancy agreement's rate. The backlit display lets the reading be read without switching on the warehouse lighting.

    Pros

    • Direct connection up to 100 A – covers most branch circuits and supplies without current transformers.
    • Backlit LCD – readings clear in a dark panel.
    • Simple check metering – a total kWh register with no communication modules or apps.
    • No configuration – works immediately once installed.
    • Wide temperature range – -10…+65 °C, suited to warm cabinets.
    • Compact – 100 x 76 x 65 mm, a standard DIN location.

    Cons / limitations

    • No communication interface or pulse output – readings can only be read on site, from the display.
    • Single tariff – day and night consumption are not calculated separately.
    • MID certificate and accuracy class are not stated in the source – check the datasheet for billing metering.
    • Three-phase networks only – a single-phase branch circuit needs a single-phase model; above 100 A a CT-operated meter is needed.
    • Fixed backlight – in some environments it may be too bright or not bright enough.

    Safety and installation notes

    • Install only with the voltage switched off, after confirming its absence on all phases and the neutral.
    • A circuit breaker matched to the conductor's cross-section is required ahead of the meter – the meter does not protect against overload or short circuit.
    • Observe the terminal marking (input / output) and phase order; if reversed, the reading will be incorrect.
    • Always connect the neutral – without it, phase voltages and the measurement are distorted.
    • Tighten the terminals to the correct torque and check them after the first load – at 100 A, a poor contact overheats.
    • Operate within -10…+65 °C; in outdoor panels, protect against cold and condensation.

    Suitable when you need:
    • check metering of a three-phase site up to 100 A without current transformers;
    • a clear reading on site – a backlit LCD in a dark panel;
    • a simple meter without communication modules or configuration.
    Check before use:
    • whether the current does not exceed 100 A;
    • whether there is a circuit breaker ahead of the meter;
    • whether the network is three-phase, 3×230/400 V, with a neutral;
    • whether the site needs an MID certificate or remote reading – if so, choose a different model.
    Important reminder:
    The meter only measures energy – it protects neither the wiring nor the equipment, so a circuit breaker ahead of it is mandatory. Only an MID-certified meter is suitable for billing a supplier; this model's readings are intended for check metering.

    FAQ

    Are current transformers required?
    No – direct connection up to 100 A, conductors connected straight to the terminals.
    Can it be read remotely?
    No – there is no communication interface; readings are read from the display in the panel.
    Does it work on a 3x220/380 V network?
    Yes – the meter is designed for both 3x220/380 V and 3×230/400 V systems.
    Is it suitable for billing a supplier?
    That requires an MID certificate, which is not stated in the manufacturer's data – check the datasheet; it is suitable for internal metering.
    Does it calculate two tariffs?
    No – a single total kWh reading is accumulated.
    Is it suitable for a single-phase branch circuit?
    No, the model is designed for three-phase networks only.
