Operating Current Derating

For continuous operation, it is

recommended that shunts are not

operated at more than two thirds

(2/3) the rated current under normal

conditions per IEEE standards for

DC instrument shunts. At ambient

temperatures above 40 °C, the current

must be further derated to prevent

damage.
