A. This is a simple three - phase four - module DIN rail - mounted electric meter with a flame - retardant ABS housing, widely used in sub - metering systems. It has a simple appearance, compact structure, good quality, and long durability. B. Features: - A three - phase four - wire meter with relatively high precision for measuring single - phase AC active energy at a rated frequency of 50 or 60Hz. - Made of flame - retardant ABS housing, with certain impact resistance, heat/cold resistance, insulation, and durability. - Small in size and light in weight, it can be installed via a 35mm DIN standard rail. - Equipped with pure copper terminals, which have good electrical conductivity and corrosion resistance, ensuring relatively stable performance under high current for a long time. C. Precautions: Due to manual measurement and different lighting conditions, there may be slight differences in size and color. Thank you for your understanding. D.
