Three-phase electronic energy meter QOLTEC EB1263816501 — DIN-rail mount, 400V, 100A, LCD

The QOLTEC three-phase electronic energy meter EB1263816501 is a DIN-rail mounted measuring instrument designed for accurate monitoring of electrical energy consumption in 400 V systems. Intended for installation in distribution boards, the meter records active energy (kWh) for three-phase networks and presents readings on a clear LCD display. It supports phase monitoring and is suitable for industrial, commercial and residential electrical installations where reliable energy measurement and straightforward DIN-rail mounting are required.

Advantages

The meter offers precise kWh measurement across three phases and a robust housing compatible with standard DIN-rail enclosures. An LCD provides clear, low-power readout of total energy consumption, and the device accepts rated currents up to 100 A without the need for external transformers in many installations. Its compact design simplifies integration into distribution panels and reduces panel space usage while maintaining stable performance in regular electrical conditions.

Suitable for

• Monitoring energy consumption in industrial distribution panels
• Commercial buildings and retail spaces requiring three-phase measurement
• Residential apartment blocks or large homes with three-phase supplies
• Energy auditing and basic load monitoring applications

Key specifications

• Supply type: three-phase (3-phase) compatible with 400 V networks
• Rated current: up to 100 A
• Measurement type: active energy (kWh)
• Display: LCD for numeric readout of cumulative consumption
• Mounting: standard DIN-rail housing for electrical distribution boards

How to use

Mount the meter on a standard DIN-rail inside the electrical distribution panel and connect the three-phase supply conductors according to the panel wiring diagram and applicable electrical standards. Ensure line and neutral connections are correctly assigned and secure all terminal screws to the manufacturer's recommended torque. After wiring, power the meter and observe the LCD to confirm consumption readings are updating. For loads near the rated current, verify that protective devices and cables are rated appropriately for 100 A operation.

Usage recommendations

Install the meter in a dry, ventilated enclosure away from direct heat sources. Follow national wiring regulations and, if needed, use professional electrical services for installation. Periodically check terminal tightness and visually inspect the LCD for correct operation; perform energy audits or recalibration against a reference meter if long-term accuracy verification is required.
