WebThe shunt current rating indicates the current that produces a full scale reading on the associated meter. Continuous currents should not exceed 80% of the shunt rating. … WebOct 30, 2024 · Shunt rating means a 300A shunt drops 75 mV when conducting 300A. At 300A it has a power dissipation of: P = 0.075V * 300A = 22.5W You never run a shunt at max current. Current is usually derated by 66%. That means maximum continuous current of a 300A shunt is 200A. When conducting 200A, shunt power dissipation is P = I^2 * R P = … hever jousting
