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.
- RS485 hardware is available. The public source does not establish a Modbus register map, so the protocol and data profile must be confirmed separately.
- Infrared, PLC, RF and cellular paths are configuration-dependent options, not standard simultaneous interfaces.
- The reviewed enclosure is IP54, measures 300 × 172 × 85.5 mm and weighs approximately 1.8 kg. Certificates and regional approvals are checked for the ordered configuration.
Typical applications
- 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
