Three-phase energy meter FF Energy-3-OPTI-100 (model WI-MEF-3-OPTI-200)

FF Energy-3-OPTI-100 (model WI-MEF-3-OPTI-200) is a three-phase energy meter designed to measure active energy consumption in three-phase electrical systems. It provides accurate, continuous metering suitable for industrial and commercial installations, allowing operators to monitor energy use, verify billing, and manage electrical loads in buildings and facilities. The meter supports standard three-phase connection schemes and is intended for fixed installation in distribution boards or energy monitoring cabinets.

Advantages

The meter delivers precise active energy measurement with stable performance under typical industrial load conditions. Its compact design enables straightforward mounting on DIN rails, while clear terminal arrangement simplifies wiring and reduces installation time. The device is built to provide reliable long-term operation for monitoring and billing applications and integrates easily into existing electrical systems.

Suitable for

• Monitoring energy consumption in factories and workshops
• Billing and submetering in commercial buildings
• Load management in multi‑tenant or multi‑circuit installations
• Integration into energy management systems and monitoring panels

Key specifications

• Measurement type: active energy (three-phase)
• Connection: standard three-phase wiring suitable for fixed installation
• Mounting: DIN rail compatible enclosure for panel mounting
• Accuracy: metering class suitable for industrial/commercial applications
• Display and interfaces: clear terminal layout for wiring and readout provisions
• Operating environment: intended for indoor electrical distribution boards

How to use

Install the meter in a distribution board on a DIN rail and connect according to the standard three-phase wiring diagram, observing correct phase sequence and protective earth connections. Ensure the supply and load are isolated before wiring. After installation, verify connections, restore power, and confirm that the meter records active energy by checking the display or readout points. Use the meter for continuous monitoring; record or integrate readings into billing or energy management systems as required.

Usage recommendations

Follow local electrical codes and safety standards during installation and maintenance. Use a qualified electrician for mounting and wiring, verify protection devices are correctly rated for the installation, and perform periodic checks to ensure accuracy and secure connections.
