IEC Fuse Blocks and Holders

These Fuse Holders and Fuse no-load Disconnectors are for use with 20x127 Ferrule-type fuses. Additionally, the modular fuse bases accommodate industrial cylindrical fuse-links 8 x 31 mm, 10 x 38 mm, 14 x 51 mm and 22 x 58 mm, Class CC and Midget (1-1/2" x 13/32") fuses. They have operating handles for non load-break disconnecting and electrical isolation for fuse-link replacement without tools. All contacts are silver-plated. 2, 3 or 4-pole units can be made up with assembly pins and operating
handle ties.
