    • An arc suppressor fixable to a fusible element to suppress electrical arcs and prevent the spread of electric arc "burn-back." The arc suppressor includes first and second inner members comprised of pre-cured silicone rubber, and first and second outer members comprised of an arc suppressing material (e.g., melamine). The inner and outer members form a sandwich around a portion of the fusible element, wherein the first inner member is located adjacent to a first surface of the fusible element and the second inner member is located adjacent to an opposing second surface of the fusible element. The first outer member is located adjacent to the first inner member and the second outer member is located adjacent to the second inner member. Mechanical fasteners tightly engage together the first and second inner members, the fusible element, and the first and second outer members.
    • 电弧抑制器可固定在易熔元件上以抑制电弧并防止电弧扩散“烧坏”。 电弧抑制器包括由预固化硅橡胶构成的第一和第二内部构件以及由电弧抑制材料(例如三聚氰胺)组成的第一和第二外部构件。 内部和外部构件在可熔元件的一部分周围形成夹层,其中第一内部构件邻近可熔元件的第一表面定位,并且第二内部构件邻近可熔元件的相对的第二表面定位。 第一外部构件邻近第一内部构件定位,第二外部构件邻近第二内部构件定位。 机械紧固件将第一和第二内部构件,可熔元件以及第一和第二外部构件紧密地接合在一起。
