4. Notice points
(1). Can't be touched the joint of the shunt and cable of primary circuit. Secondary voltage can't be sampled from non-sampling point.
(2). It won't be exceed 80% of rated current for long time working. A loop cable (or copper platoon) and shunt connection doesn't allow someone to contact resistance from the sampling point.
5. Technical data
| Accuracy class | 0.5% |
| Rated current in one time | 5A-1000A |
| Rated voltage in 2 times | 75mV |
| Environment temperature influence | Change 10℃ each, shunt output |
| Overload capacity | 120% to rated current, continue 2h |
6. Fixed setpoint shunt description
Application: The fixed setpoint shunt is a type of external shunt suitable for directly measuring the DC current below 10kA on the analog display instrument used to expand the DC current measurement range, or as a current in the sequential circuit. The standard resistor used for sampling can be regarded as the analog signal of the primary current for measurement.
