摘要: An overload current protection device for cutting off power feed from a supply to load (3) such as motor by means of contactor (switch) (2) at overloading, wherein an element (40) having magnetic impedance effect detection (4a, 4b, 4c) is used thereby expand range eliminating saturation due core, problem with conventional transformer, providing low costs wide range.
