Ordering Information
List of Models
Single-phase Voltage Relay
Shunts (Order Separately)
A shunt is a resistor to convert a DC current into a DC voltage.
Use the shunt in combination with K8AB-VW to detect undercurrent and overcurrent in DC circuits.

Note: 1. All the above listed shunts have an accuracy in the 1.0 class.
2. Select a shunt whose rated current is more than 120% of the
current normally flowing in a circuit. The characteristics of the
shunt may change or fusing of a resistor element may occur if an
overload that is 1,000% of the rated current is applied. Therefore,
determine the rated current of the shunt to be used, by taking the
circuit conditions into account.
