1 Ratings Ferraz Shawmut Class H, K and R Fuse Blocks accommodate all Class H, K and R 250 and 600V power fuses. A choice of screw, pressure plate, box and special order stud connectors fit a wide range of stranded or solid copper or aluminum wire. Insulators are either molded glass-filled polycarbonate (GFPC) or phenolic with verified dielectric strength in excess of 2500V. 30, 60 and 100A fuse blocks feature a unique adder block which can be snapped onto 1-, 2- or 3-pole blocks to form multi-pole segmented blocks of as many poles as desired. All fuse clips are made of high conductivity tin-plated copper, with a choice of spring reinforced or nonspring reinforced clips in 30A and 60A. Clips 100A and above are spring reinforced. 250VAC: 30A, 60A, 100A, 200A, 400A, 600A 600VAC: 30A, 60A, 100A, 200A, 400A, 600A Withstand ratings: 250 & 600VAC, w/classh fuses - 10kA, w/classk fuses - 50kA, w/classr fuses - 200kA Approvals All fuse blocks meet the requirements of UL Std. 512 UL Listed, Guide IZLT, File E52283 UL Recognized Component Guide IZLT2, File E52283 CSA Certified Class 6225, File Recommendes fuse usage Class R Blocks (250V) use with A2D-R, A2K-R, TR-R Class R Blocks (600V) use with A6D-R, A6K-R, TRS-R Class H & K Blocks (250V) use with OT, RF, A2Y types 1 & 3, OTN, CRN, NRN Class H & K Blocks (600V) use with OTS, RFS, A6Y types 1 & 3, CRS, NRS Clip & Connector Types 30A & 60A CLIPS CLASS R NON- 30A & 60A BOX 30A & 60A BOX 100A BOX 400A BOX IN-LINE CLIP CLASS H & K 30A SCREW 30A SCREW (R) 30A SCREW 200A BOX SIDE-CLIP 600A BOX IN-LINE CLIP NON- REINFORCED 30A PRESSURE PLATE 30A PRESSURE PLATE 400A BOX SIDE-CLIP FG36
