300 A to 500 A Standard Shunt Values
The shunt element assembly consists of two large rectangular copper terminal plates to which a
number of equal length straight Evanohm resistance wires are brazed. The current terminals are
formed at the top of the copper terminal plates with two large knobs to hold the connection cables.
Separate potential terminal binding posts are attached to the current terminal plates as well. The
shunt element assembly is attached to an insulated base plate. A perforated metal sheet is used to
protect the shunt element assembly from physical damage and to allow natural or forced air
convection.
Figure 3-2 illustrates an entire shunt assembly for the 300 A to 500 A full scale current ranges.
