A fuse assembly includes a casing having two slots defined through the first end thereof, and a conductive member is located in the casing and has a first end extending through the second end of the casing. The conductive member includes two blades with a fuse connected therebetween. A cap is detachably mounted to the first end of the casing and has a light member connected thereto. The light member has a leg portion which is electrically connected to a second end of the conductive member. The cap includes two arms which are detachably hooked to two positioning members on two sides of the casing to ensure the connection between the cap and the casing. When the fuse is burned off, the light member lights on, the cap is removed from the casing, and is detachably connected to a new casing with a functional fuse therein.

A varistor component and a method for securing a varistor component are disclosed. In an embodiment, a varistor includes a first external contact, a second external contact, a varistor electrically connected to the first external contact, a path between the varistor and the second external contact and an active releasing device including a shutter and a heat sensitive element, wherein the heat sensitive element releases the shutter under abnormal operation conditions and the shutter closes the path between the varistor and the second external contact.

Provided is a current fuse that can improve the rating while also preventing explosive scattering of metal in association with arc discharge and enabling reliable cutting off of a circuit. The current fuse (1) includes an insulating substrate (2), a main fuse element (3) disposed on the insulating substrate (2), and a sub-fuse element (4) disposed on the insulating substrate (2) and having a higher melting point than the main fuse element (3). The main fuse element (3) and the sub-fuse element (4) are connected in parallel.
