Remote integration context
Representative site context. Sensors, interfaces, enclosure, power and mounting are confirmed against the actual project before quotation.
Confirm the wiring and communication configuration
The reviewed source supports a direct-connected meter family. It does not prove that every optional communication module or protocol is installed in every unit.
- Use this selection for three-phase four-wire direct connection up to 100 A; use a CT-operated meter for higher-current circuits.
- The reviewed current range is 0.25–5(100) A, with active-energy Class 1 and reactive-energy Class 2.
- The nominal phase-voltage references are 220 / 230 / 240 VAC, with an operating range of 0.6–1.3 Un; confirm the destination wiring standard before quotation.

How to choose
- Confirm a three-phase four-wire supply, the phase voltage and whether the circuit can use a direct-connected meter.
- Use this reviewed configuration only within 0.25–5(100) A. Specify a CT-operated meter instead when the circuit exceeds 100 A or site isolation rules require it.
- State whether the data is for operational monitoring, tenant allocation or regulated billing so accuracy and certification requirements can be reviewed.
- RS485 hardware does not by itself prove Modbus compatibility. Provide the required platform, protocol and point list so the data profile can be verified.

- Facility and building sub-metering on direct-connected three-phase circuits
- Remote meter reading through a confirmed RS485 or optional communication module
- Operational energy monitoring for panels, equipment groups and distributed sites
- Import / export and multi-rate metering only when the quoted configuration includes those functions
What to include in your quote request
- Three-phase four-wire topology, phase voltage and frequency
- Maximum circuit current and confirmation that direct connection is acceptable
- Operational monitoring, allocation or regulated billing use
- Required measurements, accuracy and local certification requirements
- RS485 or optional communication path, protocol, point list and destination platform
- Meter-box space, protection, isolation and wiring constraints
- Destination country, quantity, sample / pilot / production stage and delivery target

Frequently asked questions
What does direct-connected mean for this three-phase energy meter?
The reviewed meter carries the circuit current directly through its meter terminals and is specified for 0.25–5(100) A. It does not require external current transformers within that reviewed range. Higher-current circuits need a CT-operated meter instead.
Does this meter support RS485 Modbus?
The reviewed source confirms an RS485 hardware option but does not publish a verified Modbus protocol or register map. If Modbus integration is required, include the target gateway or platform and required points in the RFQ so the protocol profile can be verified before quotation.
Is a cellular communication module built in?
Not necessarily. Infrared, PLC, RF and 2G / 3G / 4G communication paths are configuration-dependent options. The regional module, operator bands, antenna and data interface are selected and documented in the quotation.
What should I provide for meter selection?
Provide the three-phase wiring, phase voltage, maximum current, monitoring or billing purpose, required measurements, communication path, destination platform, meter-box dimensions, quantity and destination country.
What should I provide when requesting a quote for the Three-Phase Direct-Connected Smart Energy Meter?
Three-phase four-wire topology, phase voltage and frequency; Maximum circuit current and confirmation that direct connection is acceptable; Operational monitoring, allocation or regulated billing use; Required measurements, accuracy and local certification requirements
Where can I compare available model options?
Open the Industrial Monitoring Hardware Catalog linked on this page. It lists audited SG-coded selections; the ordered configuration is confirmed in the quotation.
Will it work with my existing system?
Compatibility is reviewed against your field signals, protocols and upstream platform. Typical pairings include Three-phase four-wire installations within the reviewed voltage and current range, RS485 data collectors when the selected interface and protocol are confirmed, Infrared, PLC, RF or cellular communication modules only when included in the quotation.
