220V 3 Phase Power Consumption Meters for Energy Monitoring

Track how much electricity three-phase equipment, feeders and buildings actually use with our range of 220V 3 phase power consumption meters. Designed for 220/380V and related low-voltage networks, the collection includes direct-connected meters for standard circuits and CT-operated models for higher-current installations.
Choose a basic kWh counter for straightforward local readings or a multifunction meter that measures voltage, current, demand, frequency, power factor, active and reactive power, and import or export energy. Available options include three-phase three-wire and four-wire configurations, 35 mm DIN-rail mounting, backlit LCD displays, pulse outputs, RS485 Modbus, Ethernet Modbus TCP and Wi-Fi connectivity. These meters support energy audits, equipment monitoring, tenant billing, solar generation analysis and electricity cost allocation in commercial and industrial facilities. Before selecting a model, confirm the system voltage, wiring configuration, maximum load, CT ratio, measurement direction and required accuracy certification.

Frequently Asked Questions

A 220V usage meter records the electrical energy consumed by a circuit or connected load, normally in kilowatt-hours. In a 220/380V three-phase four-wire system, 220V generally refers to the phase-to-neutral voltage, while approximately 380V is measured between phases. Buyers should confirm both voltage values because a meter must match the actual network configuration rather than the voltage of an individual appliance.

Install a compatible meter at the incoming feeder, distribution panel or individual equipment circuit. A direct-connected model carries the measured current through its terminals, while a CT-operated meter obtains current data from external transformers. Consumption can be read from the LCD, collected through a pulse output, or transmitted to an energy-management platform using Modbus, Ethernet or Wi-Fi.

Yes. A common 220/380V wye system provides about 220V from phase to neutral and 380V between phases. Some regions also use three-phase supplies where 220V is measured between phases and a neutral may not be present. Confirm the line-to-line voltage, line-to-neutral voltage and conductor arrangement before choosing a three-wire or four-wire meter.

For a balanced system, active power can be estimated using P = √3 × V × I × PF, where V is the line voltage, I is the line current and PF is the power factor. Energy consumption is power multiplied by operating time and is normally expressed in kWh. A digital meter performs these calculations continuously and measures each phase, providing more reliable data for unbalanced or changing loads.

The allowable load depends on its current input. Direct-connected products commonly support 60A, 80A or 100A per phase. Larger feeders generally use a CT-operated meter, allowing the current range to be extended by selecting suitable transformers. The CT primary rating, secondary rating, ratio and conductor opening must match the installation. Cable and breaker ratings must also be calculated independently.

Check the phase-to-phase and phase-to-neutral voltages, three-wire or four-wire configuration, maximum current and required measurement direction. For CT-operated models, verify the CT ratio and whether the meter accepts 1A, 5A or dedicated sensors. Other useful comparison points include accuracy class, MID eligibility, DIN-rail width, LCD visibility, pulse output, Modbus compatibility, Wi-Fi monitoring and support for bidirectional energy measurement.
