It is a simple three-phase four-module DIN rail meter with a flame retardant ABS housing that is widely used in sub-metering systems. Simple appearance, small size, high quality and durable. Features: High-precision three-phase four-wire energy meter, specially designed for measuring single-phase AC active energy with rated frequency 50 or 60Hz. High quality flame retardant ABS shell with good impact resistance, heat/cold resistance, insulation and durability. 6+2-digit backlight LCD display, the meter counts accurately and clearly displays the energy consumption. Using 35mm DIN standard rail installation, small size,light weight, lighter weight, more convenient installation. Pure copper terminals, with excellent electrical conductivity and corrosion resistance, can ensure long-term work with high current. Note: Size and color may vary slightly due to manual measurements and different lighting conditions. Thanks for your understanding.
