NOVELTY - The utility model claims a protector, comprising a shell, a base, a connection terminal, a shell, a base and a connection terminal are assembled together to define an internal space, packaging a thermosensitive element and a movable arm in the interior space and abutted with each other, and mutually matched static contact and a movable contact, a static contact fixed and arranged in the inner space, the movable contact is arranged on the free end of the movable arm. drives the movable arm through thermal deformation of the sensitive element, capable of realizing contact or separation of the moving contact and the fixed contact, and moving one or both of contact and static contact in the graphene/silver-based composite material. through the graphene/silver-based composite material movable contact and/or the fixed contact, which can effectively reduce the contact resistance between the contacts and improve the temperature rise of the contact, improves the hardness of the contact surface and the contact resistance, electric arc ablation resistance, so as to improve electric performance and service life of the protector. The utility model further claims an electric device capable of mounting the protector.
