Why Choose the ABB D11 15-M 40 Energy Meter?
The ABB D11 15-M 40 is a compact single-phase direct-connected energy meter designed for accurate electricity measurement in residential, commercial and building-services installations. Part of ABB's D11 EQ meter range, it provides direct measurement up to 40 A while occupying only one DIN module, making it particularly useful where distribution-board space is limited.
The D11 15-M 40 provides four-quadrant energy measurement, allowing active and reactive energy to be monitored in both import and export directions. Active energy measurement meets Class B accuracy under the MID framework, while reactive energy is measured to Class 2, supporting dependable monitoring of both electricity consumption and locally generated energy.
This version is designed without an integrated serial communications protocol, making it a straightforward choice where local metering and pulse-based integration are required. It includes one digital input and one digital output, supports two-tariff operation and provides an electrical S0 pulse output for connection to compatible monitoring or data-acquisition equipment.

Compact Direct-Connected Single-Phase Energy Monitoring
The ABB D11 15-M 40 provides direct energy measurement on single-phase circuits up to 40 A without requiring external current transformers. Its single-module construction allows accurate metering to be added to compact consumer units and distribution boards while minimising the amount of DIN-rail space required.
Four-quadrant measurement enables the meter to distinguish energy flow in both import and export directions, making it suitable for conventional loads as well as installations with local generation. The digital input, digital output and electrical S0 pulse functionality provide practical options for tariff control and connection to external energy-monitoring equipment without requiring an integrated serial communications network.
