In fuse holder, the fuse base and fuse carrier are made of highest grade phenolic moulding confirming to IS : 1300 which have lightness non-hygroscopic, non-inflameable and good tracking resistance properties. The carrier contacts are made of phosphor bronze to give good springiness throughout the service life. The spring action holds the fuse firmly giving good electrical contact and prevents the fuse carrier from coming out of fuse-base due to vibration. Aperture giving visible indication of operation of HBC fuselinks in mounted position.
