This is a simple counter to Three-phase four-module DIN rail with flame-retardant ABS enclosure, which is widely used in sub-metering systems. It is concise in appearance, compact in size and good in quality, durable to use. Features: 1.The three phase 4 high precision wires is designed for the measurement of single-phase active electricity at nominal frequency 50 or 60 Hz. 2.High quality flame retardant ABS case with good impact resistance, heat/cold resistance, insulativity and durability. 3.With 6+2 digit backlit LCD display, the meter accurately counts and clearly displays power consumption. 4.Adopts 35mm DIN standard guide rail installation, compact size and light weight make installation easier. 5.The copper wiring terminal pure with excellent conductivity and corrosion resistance can ensure high current for long time performance. Note:Size and color may be slightly different due to manu measurement and different lighting conditions. Thank you for your understanding.
