PROTECTIVE ELEMENT

Abstract: a protective element includes: a first fuse element part including a first fuse element; a second fuse element part including a second fuse element; an insulating enclosure having a fusing space in which the first fuse element is positioned and a cutting space in which the second fuse element is positioned; and a slider disposed to be movable within the fusing space toward a second fuse element side. the fusing space is divided into a first space and a second space which interpose the slider, the first fuse element being positioned in the first space, and a second space being connected to the cutting space. when a fusion current flows to the first fuse element, and as pressure in the first space rises, the slider is configured to move toward a second fuse element side such that a cutting part of the slider cuts the second fuse element.
