Mode G Series Shunt

General Description

Shunt resistance,shunt resistor current measurement,current shunt,current sensing shunt.

Shunt is one of the main current sensor used in kWh meter, especially in single phase kWh meter.

Electron beam weld shunt is a new technology product. E-B weld has strict requirement to manganin and copper materials, the shunt by E-B weld is in high quality. E-B shunt is more and more popular and extensively used to replace the old braze weld shunt worldwide.
