Busbar Shunts
Busbar Shunts designed for switchgear applications. High accuracy at +/- 0.25%. Busbar Shunts have multiple blades for a cooling effect and can be mounted directly to a bus bar.
Typical applications include battery chargers, electroplating, heavy industry, mining, solar generators, and wind power.
Available options include Certificates of Calibration or Certificates of Conformance, if required.
Advantages of Direct current (DC) instrument shunts are that the units are used to extend the range of ammeters whenever the current to be measured is too large to be passed through the instrument–usually currents over 50 amperes. The DC shunt, therefore, is a diverter which is used to “shunt” the majority of the current around the indicating instrument. Essentially, the DC shunt is a specially-designed resistor which delivers a millivolt output (to a millivolt meter or instrument) in proportion to the current flowing through the resistor.
