Resistive Current Shunts
The Resistive Current Shunt is designed for permanent applications as a interface from the CT secondary wiring to a Weis FR100 series Fault Recorder.
 The shunts compact design makes it ideal for mounting within fault recorder panels. It also offers an excellent level of overload withstand at 150A continuous and 300A pulsed.
Being resistive rather than inductive, greater levels of accuracy in terms of phase angle and magnitude are possible, particularly in applications where Distance to Fault calculations are to be made.
Ranges: 1.0A up to 12.5A nominal.
