This is a simple three-phase four-wire DIN rail meter with a flame-retardant ABS casing, widely used in sub-metering systems. Its concise appearance, compact size, and good quality make it durable for use. Features: High-precision three-phase 4-wire energy meter designed to measure single-phase AC active electricity at a rated frequency of 50 or 60 Hz. High-quality GXY flame retardant ABS casing offers good impact resistance, heat/cold resistance, insulation, and durability. With a 6+2 digit backlit LCD display, the meter accurately counts and clearly shows energy consumption. Adopts standard DIN 35mm guide rail installation, compact size, and light weight for easier installation. The pure copper wire terminal with excellent conductivity and corrosion resistance ensures large current for long-lasting performance. Note: Size and color may vary slightly due to manual measurement and different lighting conditions. Thank you for your understanding.
