A fuse holder is an important component of a reliable and safe circuit protection because it is a safe place to locate the fuse itself when in an electrical system or wiring appliance. The fuse holder is the designated point of connection for the fuse itself and guarantees safety and stability when a fuse is needed to interrupt the circuit. Without an appropriate fuse holder, the fuse may not make appropriate contact with the circuit and thus risks overheating, arcing, and possibly an electrical fire.
A fuse holder contributes to safety when replacing or maintaining the fuse. Again, a fuse holder is specifically designed to help technicians easily remove and replace a tube fuse within a safe environment without having to come in contact with live electrical contacts, and possibly experiencing an electrifying shock or an unintentional short circuit. Many modern fuse holders will have insulation incorporated as an additional layer of safety; they may also have locking mechanisms or covers as well.
