Product information

Description

The 3-phase Energy Meter ET340 REL300300000 OEM with LCD display is designed for measuring active electrical energy in three-phase power systems. It provides phase-by-phase energy measurement with a local LCD readout showing cumulative energy and basic electrical parameters. The meter is intended for OEM integration into switchboards, control panels or equipment where compact, accurate energy monitoring and support for centralized billing or energy management are required.

Advantages

The ET340 delivers accurate measurement of active energy across three phases and presents results on a clear LCD, enabling quick local verification. Its OEM form factor makes it suitable for mounting in panels and integrating into larger electrical installations. The device supports centralized monitoring scenarios by providing standardized energy values and consistent phase-specific readings, helping to identify imbalances and consumption patterns.

Suitable for

  • Industrial facilities and manufacturing plants requiring three-phase energy metering
  • Commercial buildings, retail centers and office complexes with centralized energy management
  • Large residential buildings or multi-dwelling units where aggregated billing or monitoring is needed
  • OEM panel builders and equipment manufacturers integrating energy measurement into switchboards

When it may not be suitable

The ET340 is specifically intended for active energy measurement in three-phase systems and may not be suitable for applications that require multi-parameter power quality analysis (such as harmonic distortion measurement, transient capture or advanced waveform analysis). It is also not suited for single-phase installations unless additional wiring or adapters appropriate for three-phase measurement are used.

Key specifications

  • Measurement type: active electrical energy in three-phase systems
  • Display: local LCD for cumulative energy and basic electrical parameters
  • Form factor: OEM panel-mount compatible design for integration
  • Phase measurement: individual phase-by-phase energy readings
  • Intended environments: industrial, commercial and large residential installations

How to use

Install the ET340 into the designated cutout of a control panel or switchboard following the manufacturer’s mechanical and electrical mounting guidelines. Connect the phase and neutral conductors to the meter’s input terminals according to the wiring diagram, ensuring correct phase sequence and secure terminal connections. Once powered, the LCD displays cumulative active energy and available basic parameters; read values locally or feed the outputs/signals to your building energy management system if integration points are provided. Follow all local electrical codes and safety procedures during installation and commissioning.

What to consider before purchase

  • Verify that your installation is a three-phase system and that the meter’s input and mounting format match your panel layout
  • Confirm the meter provides the specific readouts and integration options required by your billing or energy management system
  • Ensure compatibility with your local electrical codes and any protection or isolation requirements
  • Plan for installation access and any additional accessories or current transformers if needed for your current range

Usage recommendations

For reliable long-term operation, mount the meter in a dry, ventilated panel away from direct heat sources, verify phase connections at initial commissioning, and schedule periodic verification against a reference meter to ensure ongoing measurement accuracy.
