2CMA100240R1000 ABB A41 113-100 Single-Phase Direct-Connected 80 A Energy Meter with M-Bus

Why Choose the ABB A41 113-100 Energy Meter?

The ABB A41 113-100 is a compact and accurate single-phase direct-connected electricity meter designed for active energy measurement in commercial, industrial and building-services installations. As part of the ABB A41 energy meter series, it combines direct measurement up to 80 A with a clear backlit digital display and integrated M-Bus communication.

Designed for direct connection to single-phase circuits, the A41 113-100 measures active energy with Class B (Class 1) accuracy. It also displays useful instrumentation values including power, current, line-to-neutral voltage and frequency, allowing the meter to provide both accumulated energy information and operating data for the monitored circuit.

The meter operates across a wide 57.7–288 V AC voltage range and incorporates an M-Bus interface for remote energy-data collection. A configurable output can be used for energy pulses or alarm signalling, while up to 25 alarm conditions can be configured. Its four-module DIN-rail format, infrared interface and IEC and MID approvals make it well suited to professional energy-monitoring and sub-metering installations.
