Shunts - Class 0.5, Class 1.0   Shunts are used for measuring currents in DC installations. Shunts provide proportionate voltage drop of 50mV / 60mV / 75mV / 150mV for the current. These high currents can be then measured with a PQ / PL movement. Shunts are made of manganin resistance element of high accuracy which produce proportional voltage drop when current passes through them due to temperature coefficient of 0.002%/K     Form A Form B Form C   Selection Chart Measured Current Voltage Drop Type Form A Form B Form C 1A - 150A 50mV / 60 mV / 75mV / 150mV 151A - 3000A 50mV / 60 mV / 75mV / 150mV 3001A - 15000A 50mV / 60 mV / 75mV / 150mV     Accuracy Class - 0.5 or 1 as per IEC51   Reference Temperature: 23C   Permissible Overloads   - 1.2 times rated current continuously - 5 times rated current for 5 second up to 2000A - 2 times rated current for 5 second for 2000A to 10000A
