Toroid shielding SCH

In large systems, when busbars are used or there are many cables, it may happen that it is not possible to center the active conductors and pass close to the internal casing of the toroid. This does not represent correct installation since, in the event of high inrush or high load currents, an incorrect reading of the differential current may occur and consequently untimely trips. This screen, built with a special ferromagnetic material (MuMetal) prevents the saturation of the toroids, reducing/eliminating the problem.
