Description

The R100-BAR-12A shunt resistor is a precision Cu-Mn resistance. It consists of a copper busbar with hole terminals for easy installation and four solderable pin-type sense contacts providing fully redundant sensing of the electric current via shunt voltage.

The shunt is designed for precision current measurement with highest safety level, high thermal stability in industrial, and particularly automotive applications, typically including power inverters, motor control, and battery current monitoring with most demanding safety
requirements.
