Abstract: An electrical fuse holder for mounting a cartridge fuse comprises a panel-mountable body of insulating material formed with a central slot of a size allowing the passage of a fuse from an access aperture until its caps engage in respective contact members. The fuse is resiliently held in a carrier of insulating material provided with outwardly extending resilient catch portions that engage lips on the body member to retain the carrier in position. Finger pressure on the accessible portion of the carrier releases the catches from the lips to allow withdrawal of the fuse.
