G3A.144-230.F14 – a Lithuanian-made ELGAMA-ELEKTRONIKA GAMA 300 series three-phase electronic energy meter, direct connection up to 100 A, 3×230/400 V, with 4 tariffs, active energy metering, maximum demand registration and load profiles. Designed for billing metering and check metering in residential homes, commercial premises and small- to medium-power industrial supplies, where the energy meter is mounted in the incoming panel without current transformers.

Key idea:
An incoming meter has to withstand the full current of the site, calculate tariffs accurately and remain reliable for decades in an outdoor panel – it's not a monitoring device, it's the basis of the billing. GAMA 300 belongs to the same family that ESO uses on a mass scale for billing metering in Lithuania, so its construction, climatic resistance down to -40 °C and UV-stabilised polycarbonate enclosure have been proven under exactly these conditions. The F14 version calculates active energy across four tariffs and additionally registers maximum demand and a load profile – what both the supplier and a consumer wanting to understand their load actually need.

What makes the G3A.144-230.F14 worthwhile?
For the consumer it means transparency: four tariffs let you see precisely how much energy was used in cheap and expensive hours, while P max and the load profile show when the site is under the heaviest load. For a supplier or administrator, it's a proven Lithuanian-made device with LST EN 62052-11 and LST EN 62053-21 standard approval, suitable for billing.

• Active energy metering – total and per-tariff kWh registers for billing and check metering.
• 4 tariffs – energy accumulated separately by time zone, per the internal clock's schedule.
• Maximum demand registration – P max captures the highest average power, important for the demand charge and for assessing the size of the supply.
• Load profile – a consumption history by time interval, for analysing the site's load.
• Instantaneous values – current, voltage, kW and kVAr for each phase, right on the display.
• Data reading – can be connected to a remote reading system; the data reading interface depends on the specific meter configuration.

• Three-phase supplies up to 100 A for houses and homesteads
• Metering for apartments and common areas in blocks of flats
• Commercial premises, shops, cafés and offices
• Small and medium-power workshops and production premises
• Farms, warehouses and agricultural sites
• Check metering for tenants in business centres
• Outdoor incoming panels and metering cabinets

A café with a 63 A three-phase supply pays under a single-tariff plan. After installing the G3A.144-230.F14 and collecting the 4 tariff registers over a month, it emerges that 1,850 kWh out of 3,200 kWh is consumed in the night and weekend zones (refrigeration equipment), while P max reaches only 28 kW out of the available 43 kW. The result: switching to a four-time-zone plan cuts the bill by about 12%, and there's no need to increase the supply – the decision is made not by guessing, but from the meter's data.

• Installation and connection work is carried out by a qualified electrician with the voltage switched off; for billing metering, the meter is sealed by the supplier.
• Incoming protection ahead of the meter must not exceed 100 A – the meter itself does not protect the circuit.
• Choose the conductor cross-section to match the full supply current and the manufacturer's stated terminal capacity; tighten to the specified torque.
• Observe the phase sequence and terminal marking per the manufacturer's diagram – an incorrect connection distorts the readings.
• Install vertically in a metering cabinet or panel; ensure the IP51 rating through the cabinet's protection against direct water.
• Configure the tariff clock and the P max period before commissioning; changing it later may require the seals to be removed.

Quick selection guide

Does this meter calculate reactive energy?
No – the F14 meters active energy only; for reactive (R+, R-), choose the G3A.144-230.F34.

Are current transformers required?
No, up to 100 A the meter is connected directly.

What are the 4 tariffs?
Four separate energy registers, into which energy is accumulated according to the internal clock's schedule – e.g. day, night, weekend, peak.

What does P max show?
The highest average active power over the integration period – used to assess the adequacy of the supply and the demand charge.

Is it suitable for billing with ESO?
The GAMA 300 family is used for ESO metering, but for billing, the meter installed and sealed by the supplier applies. The base F14 code alone does not confirm MID/metrological configuration; billing metering requires the metrological compliance of the specific unit.

Can data be read remotely?
The manufacturer states the option to connect to a data reading system. The data reading interface depends on the specific meter configuration, so confirm it when ordering.
