The ABB B24 113-100 is a compact three-phase DIN-rail energy meter with M-Bus communication, designed for accurate submetering and cost allocation in commercial and residential installations. Its backlit digital display and intuitive navigation make on-site reading straightforward, while the 4-module footprint saves space in crowded distribution boards.

Engineered for transformer-connected systems, the meter accepts a 1 A CT input and supports 3- and 4-wire networks. It operates on 220–240 V AC (N–L), 50/60 Hz, and provides Class B MID accuracy (±1%) for active energy. Integration is simplified via wired M-Bus and a configurable digital output for pulses or alarms; extensive instrumentation values, up to 25 alarms, event logs, and a 7-digit counter enable robust monitoring. Built for panel environments, it mounts on DIN rail, offers IP20 protection, handles ambient temperatures from -40 to +70 °C, and accepts 0.5–10 mm² conductors.

Whether used for tenant billing, energy management, or facility analytics, the B24 113-100 delivers reliable metering compliant with IEC and MID requirements, helping you standardize across projects while minimizing maintenance—confidence further supported by a 1-year warranty.
