Itacoil’s current measurement transformer. It allows measuring a maximum rated current of 42.5 A (maximum allowed value 51 A) with an accuracy class of 0.2. The Burden resistance (shunt) to be used is 50 ohms. If you need to measure higher currents (but do so at the expense of accuracy), you can get up to 51.6 A nominal (the maximum allowed value is 62 A) but the Burden resistance value becomes 5 ohms. We have opted for the first case, ie a nominal current of 42.5 A and therefore greater precision.
