Kilowatt-hour meters, also known as energy meters, watt-hour meters, or electricity meters, are essential devices for measuring electrical energy consumption in residential, commercial, and industrial installations. These meters quantify active energy in kilowatt-hours (kWh) and can be designed for single-phase or three-phase systems, with direct connection or via current transformers (CT) for higher currents. Key technical specifications include accuracy class (typically Class 1 or Class 2 for general use, or Class 0.5 for billing), rated voltage (e.g., 230V AC for single-phase, 400V AC for three-phase), rated current (e.g., 5(80)A for direct connection), frequency (50/60 Hz), and communication interfaces such as pulse outputs, Modbus RTU, or M-Bus for remote reading. They are available in DIN-rail mountable enclosures for panel integration or socket-type designs for utility metering.

These meters are deployed in electrical distribution panels, main switchboards, and sub-distribution boards for energy monitoring and billing. In industrial automation, they are integrated into power management systems (PMS) and building management systems (BMS) to track consumption, detect anomalies, and optimize energy efficiency. Common sectors include utilities for grid metering, manufacturing plants for process monitoring, commercial buildings for tenant sub-metering, and renewable energy installations for net metering.

Subcategories include single-phase kWh meters (e.g., models with codes like EM100-1P or ME382), three-phase direct meters (e.g., EM300-3P or ME442), and CT-operated meters (e.g., EM400-CT or ME483). Typical article codes follow patterns such as "EM-XXX-YYY" where XXX denotes phase type (1P, 3P) and YYY indicates current rating or communication option. For example, EM-1P-80A represents a single-phase meter rated at 80A. Other variants include prepayment meters and multi-tariff meters with time-of-use registers.

Partnering with Electric Automation Network ensures access to a comprehensive range of kWh meters from leading manufacturers, with real-time pricing and stock availability. Our engineering team provides technical support for selection, configuration, and integration with energy management systems. We offer express worldwide shipping, ensuring fast delivery for critical projects. Documentation, including wiring diagrams and communication protocols, is available for each article.
