Asea Brown Boveri 2CMA170510R1000 Panel Meter

ABB 2CMA170510R1000 corresponds to the A42 112-100 single-phase energy meter, a DIN-rail mounted, steel-enclosed panel meter from ABB used for tariffing and energy allocation in commercial and industrial circuits. It measures active energy along with voltage, current, and frequency, and presents readings on a large, backlit pixel-oriented LCD display; it also supports Modbus RTU communication over RS-485 for integration with building management or energy management systems. This meter is intended for indirect measurement via a current transformer (CT) with a 6 A secondary, operates on 50/60 Hz power, and accepts a voltage input range of 57–288 V AC, making it suitable for a wide range of European and other installations; a pulse output is available for metering signals. MID certified, the device is designed for revenue-grade metering in panel environments, with reliable DIN-rail mounting and ABB’s emphasis on compact, accurate single-phase metering. The A42 112-100 family is known for precise energy measurement (Class 1) and flexible communications, delivering a practical solution for on-site energy monitoring, cost allocation, and sub-metering in low- to mid-power applications.
