ABB B23 ENERGY METER 'SILVER', IR PORT, THREE-PHASE, 5A B23-311-100

The B23-311 energy meter is a direct connect device designed for three-phase systems. It has a maximum current rating of 65A and operates at 230VAC. This energy meter features two output ports and two input/IR ports, providing flexibility for connectivity. In terms of accuracy, the active energy measurement has a class 1% accuracy, while the reactive energy measurement has a class 2% accuracy. The range of measurement for voltage is 220-240V between neutral and line (N-L), and 380-415V between line to line (L-L). The meter has an IP20 protection degree, ensuring it is protected against solid objects larger than 12mm in diameter. Additionally, it is equipped with a backlit pixel-oriented LCD display for easy reading in various lighting conditions. As part of the Silver functionality sub-group, this energy meter offers several features including active, reactive, and apparent energy measurements. It also supports import/export of energy, resettable energy registers, and different classes of accuracy (either Class 0.5 or Class 1). Tariffs can be configured as well. The meter supports fixed I/O connections and provides information on active energy consumption. It also offers pulse output/alarm functionality. With a width of four modules, this energy meter can be easily mounted on a DIN rail for convenient installation.
