Accuracy Level: 2-4000A, 0.5 level 5000-10000A, 1 level. Environmental Conditions: -40 - and60 Celsius, relative humidity less than or equal to 95 percent (35 Celsius) Overload Performance: 120 percent of rated current, 2 hours Load Heat: Temperature rise changes stabilized, rated current of 50A following does not exceed 80 Celsius rated current above 50A does not exceed 120 Celsius. Color: Black Material: Metal Voltage Drop: 75mV Weight: 128g The fixed shunt resistor is a suitable attached external shunt for measuring DC current in 10kA less direct-acting on the analog display instrument, used together to expand the range of DC current measurement, or sequential circuit can be considered as current sampling with standard resistors, a sampling voltage is measured with a current that can be considered as an analog signal. Package Contents: 1 x 100A 75mV DC shunt resistor (resistor only, voltage apparatus not included) Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The allowed measurement error is 1-3 cm.
