This page explains how Energy Meter is classified within Electrical Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
An energy meter, also known as an electricity meter or watt-hour meter, is an electrical instrument that measures the amount of electric energy consumed by a residence, business, or electrically powered device.
Technical details and manufacturing context for Energy Meter

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The accuracy class is 1.0, as per IEC 62053-21. This indicates a permissible error of ±1% under specified conditions. Always confirm the exact accuracy for your application with the manufacturer.
While it is a three-phase meter suitable for commercial or industrial use, it can also be used in residential settings with three-phase supply. However, local utility regulations may require specific certifications or accuracy classes. Verify with the utility and manufacturer.
It supports Modbus-RTU, a widely used serial protocol for industrial automation. This allows remote reading and integration with energy management systems. Ensure your system is compatible with Modbus-RTU.
The operating temperature range is -25 to 55 °C, storage -40 to 70 °C, and humidity up to 95% RH non-condensing. The housing is IP54, meaning protection against dust and splashing water. Do not expose to condensing conditions or outdoor environments without additional protection.
