safety

A ground fault circuit breaker is an electrical safety device which must have both extreme sensitivity to effectively prevent electrical accidents and a small size to facilitate integration inside distribution cabinets.
For these reasons, the electromagnetic parts, i.e. the core and the relay, are made from materials with very high permeability and high saturation induction, such as Supra 50 and the Permimphy grades.
