Three-phase Electric Watt-hour Meter

DT862 Three-phase Electric Watt-hour Meter
Description:
The DT862 three-phase electric watt-hour meter (four-wire) is designed to meet the latest IEC60521 standards for measuring active energy in three-phase four-wire alternating current power grids. Connection is direct or by instrument transformers. DT862 three-phase electric watt-hour meter has an average service life of 10 years and maximum overload capacity of 600%Ib.
Structure and Features of Three-phase Electric Watt-hour Meter:
1. Meter case
It meets the protection requirements set by protection class IP53 of IEC60529.
2. Terminals & Terminal block
Terminals:
