Multitek M600-WM9 Three Phase Kilowatt Hour Meter

The Multitek M600-WM9 is a three-phase kilowatt-hour meter designed for systems with unbalanced loads, delivering kWh measurements across all three phases. It operates at 277/480 volts and 60 Hz in a 3-phase, 4-wire configuration, making it compatible with a wide range of commercial and industrial power distributions. This unbalanced-load kWh meter captures energy usage per phase and aggregates it to provide total consumption, supporting energy accounting, load management, and billing in environments where voltages or currents are not perfectly matched. The M600-WM9 is intended for installations that require reliable, ongoing monitoring of electrical energy in a 4-wire 3-phase network, such as offices, manufacturing facilities, or data centers that employ 277/480 V systems. Common use cases include monitoring energy consumption for commercial lighting, equipment, and process loads on unbalanced 3-phase systems.
