AIR COOLED DC SHUNTS 
Air Cooled Shunts Type 4640

4640 Air Cooled Precision DC Shunt.
The 4640 range of Air Cooled Precision DC Shunts offers good accuracy at low cost. 

Available in four resistance values and a range of Full Load operating currents from 50 Amperes to 1,000 Amperes. These instruments are manufactured from selected Manganin, specially heat treated for low temperature coefficient and long term stability. The instruments are constructed using a non-metallic base board with the elements protected by a mesh cover allowing good air flow to cool the instrument. 



4640 Air Cooled Precision DC Shunts

For prolonged use under full load conditions we recommend forced air cooling to preserve best accuracy. 

These current shunts are designed to have minimum inductance and use the four terminal measurement principal. 

They are suitable for use with DC and also AC at power frequencies. 
Instruments are supplied with calibration certificate.
