Keystone Fuse Holder
A fuse holder is a device for holding and securing a fuse in an electrical circuit. It has a base which is connected to the circuit and two terminals connected to the fuse. Fuse holders provide a convenient way to connect, remove and protect fuses for safety and proper circuit protection. They come in a variety of styles, all designed with the purpose of making it easy to secure and disconnect a fuse from an electrical circuit. Fuse holders also provide some degree of insulation from the electricity in the circuit, helping to prevent electrical shock during maintenance or inspection.
