## Summary description

The ETI DEC-3 is a modular 3-phase electricity meter designed for DIN-rail installation in distribution boards. It provides metering of three-phase electrical consumption suitable for residential, commercial or light industrial installations. As a modular unit, it integrates into switchgear to monitor energy usage and assist with billing, load management and system diagnostics.

## Long description

The ETI DEC-3 is a modular 3-phase electricity meter designed for DIN-rail installation in distribution boards. It provides accurate metering of three-phase electrical consumption for residential, commercial and light industrial installations. The compact modular design allows the meter to fit into switchgear assemblies, enabling centralized monitoring of energy usage, load tracking and simple integration into distribution systems.
Advantages
The meter offers three-phase active energy measurement in a single modular unit suitable for DIN-rail mounting, which saves space inside distribution boards and simplifies installation. Its clear display and standardized electrical connections facilitate readout and wiring during commissioning and routine checks. As a dedicated energy meter, it supports basic load management and billing tasks while providing stable performance for continuous operation.
Suitable for
DIN-rail distribution boards in apartments, houses and multi-dwelling buildings
Small commercial premises and light-industrial facilities requiring three-phase consumption monitoring
Energy monitoring and sub-metering within switchgear installations
Load verification and basic billing tasks where a modular meter format is required
When it may not be suitable
This modular meter is intended for direct DIN-rail installation in distribution panels and is optimized for standard three-phase metering. It may not be appropriate where advanced communication protocols, remote telemetry or high-resolution power quality analysis are required, as it is designed primarily for basic three-phase energy measurement and local readout. For installations needing advanced networked integration or detailed diagnostics, a meter with expanded communications and analytics capabilities should be considered.
Key specifications
Measurement: three-phase active energy (kWh)
Mounting type: DIN-rail modular form factor for distribution boards
Display: integrated local display for reading consumption values
Connection type: standard screw/terminal connections for line and load conductors
Application class: suitable for residential, commercial and light industrial use
How to use
Install the modular meter onto a standard DIN-rail inside the distribution board following local electrical codes and safety practices. Connect the three-phase supply and load conductors to the appropriate terminals and secure the neutral and protective earth according to the wiring diagram. After powering the unit, verify the display and measured values against known loads. Use the local display for consumption checks and periodic readings; for billing or monitoring purposes record values at defined intervals. Ensure a qualified electrician performs installation and verification.
What to consider before purchase
Confirm compatibility with the distribution board space and available DIN-rail mounting slots
Verify that three-phase direct connection metering meets the installation's measurement and billing requirements
Check whether additional communications or remote monitoring capabilities are needed beyond local readout
Ensure the device's electrical ratings (voltage/current range) match the site's supply and load characteristics
Usage recommendations
Install and commission the modular meter as part of a coordinated distribution board layout; label circuits clearly and record initial meter readings. Perform periodic visual inspections and verify readings during maintenance intervals. If remote monitoring or integration into building management systems is required, plan for a compatible communication gateway or choose a meter with native communications.
