## Summary description

Three-phase energy meter QOLTEC 50980 measures electrical energy in three-phase systems up to 400 V and 100 A and includes a reset function. Designed for monitoring consumption in commercial or residential installations, it provides accurate kWh measurement for billing, load tracking and energy management. Suitable for panel mounting and integration into distribution boards.

## Long description

The QOLTEC three-phase energy meter 50980 measures active electrical energy in three-phase installations with a rated voltage up to 400 V and a rated current up to 100 A. Designed for panel mounting and integration into distribution boards, the meter records kWh values and includes a reset function that allows clearing cumulative energy data when required for periodic monitoring or temporary measurements. The device is intended for monitoring consumption in residential, commercial and light industrial environments where accurate active energy measurement and compact DIN-rail compatible mounting are needed.
Advantages
The meter provides precise kWh measurement for three-phase systems and supports direct connection up to 100 A without additional transformers in many typical installations. Its reset function enables simple clearing of accumulated energy values for temporary tests or interval-based readings. Compact housing and DIN-rail compatibility facilitate installation into distribution boards, while a clear display ensures easy reading of energy values and reset status.
Suitable for
Monitoring electricity consumption in multi-apartment or commercial distribution panels
Tracking energy use for tenant billing, cost allocation or submetering
Temporary measurement campaigns and interval-based energy checks using the reset feature
Integration into electrical panels where space is limited and panel-mounted meters are required
Key specifications
Supply: three-phase systems with nominal voltage up to 400 V
Nominal current: direct connection up to 100 A
Measured quantity: active energy (kWh)
Reset function: allows clearing cumulative energy reading for temporary measurements
Mounting type: DIN-rail / panel mounting compatible
Display: numerical readout for cumulative energy and reset indication
How to use
Mount the energy meter on a compatible DIN rail inside the distribution board and connect the three-phase supply conductors according to the installation diagram provided by QOLTEC or a qualified electrician. Verify correct phase sequence and secure connections for currents up to 100 A as applicable. After power-up the display shows cumulative active energy; use the reset control to clear the accumulated value when performing temporary measurements or interval readings. Regularly check terminal tightness and the display to ensure ongoing measurement reliability.
Usage recommendations
Installation and wiring should be carried out by a qualified electrician in accordance with local electrical codes. For installations approaching the nominal current limit, confirm conductor sizing and connection method to avoid overheating. Use the reset function only when appropriate for measurement procedures and record readings before clearing where permanent billing data are required.
