FL-21 600A 75MV Current Shunt DC Shunt
Product Name: Shunt
Environmental Conditions: -40℃ to 60℃

Product Model: FL-21
Accuracy Level: 0.5 level for 1–4000A; 1 level for 5000–15000A

Overload Performance: 120% of rated current
Relative Humidity: ≤95% (at 35℃)

Voltage Drop: 60mV
Overload Capability: 120% of rated current for 2 hours

Notes:
No artificial contact resistance is allowed at the connection points between the primary circuit cable (or copper busbar) and the shunt. The secondary voltage sampling point must not be taken from non-sampling points.
This fixed-value shunt is rated 0.5 level with a nominal voltage drop of 275mV. It is used in DC circuits in combination with a 75mA magnetoelectric millivoltmeter to extend the instrument's current measurement range.

Heat Rise Under Load:
After temperature stabilizes:

For rated currents up to 50AU, temperature shall not exceed 80℃.

For rated currents above 50AU, temperature shall not exceed 120℃.

Secondary Voltage Drop Options:
50mV, 60mV, 75mV, 100mV, 150mV, 200mV, 300mV, etc. Default is 60mV.
