Blocks and Holders Fuse Blocks General Information 4. Determine if NEC, CSA, UL, or other requirements are applicable If fuse blocks will be installed in equipment to be submitted for agency approval, the requirements should be obtained from the approving agency in advance of fuse and fuse block selection. 5. Select the type of wire termination A choice of three types of wire termination is available: a) Screw* — for use with spade lugs or ring terminals. b) Screw with Pressure Plate* — for use with solid or stranded wire without terminal. Recommended where vibration will be a factor. c) Box Lug — the most durable. For use with all types of solid wire and Class B and Class C stranded wire. Not for use with welding cable or other rope-stranded conductors. * 1/4” Quick Connect terminals rated for up to 20A are available on the Midget and Class CC fuse blocks. Fuse Block Selection The following guidelines should help simplify the selection of proper fuse blocks: Screw with Pressure Plate (P) 1. Determine the system voltage Since fuses are selected on the basis of sys­tem voltage, fuse blocks are selected to match the voltage rating of the fuse. Screw (S) Box Lug (C) 6. Decide on the number of poles in each block 2. Determine the design short-circuit current Class H fuse blocks will accept Class H or K5 fuses (which have an interrupting rating of up to 50,000 amperes) and Class R fuses (which have a 200,000 A.I.R.). To prevent the possibility of inserting a fuse with the incorrect in­ter­rupt­ing rating, the use of Class R fuse blocks is recommended for use with Class R fuses. Use Class H fuse blocks with Class H or K5 fuses. These fuse blocks are dimensionally the same, but the Class R fuse blocks incorporate a rejection feature which allows only Class R fuses to be inserted. The number of poles for each set of fuses is determined by the characteristics of the circuit. The option to gang individual fuse blocks into long strips will be determined by the avail­able space and by the type of wire being used. Blocks and Holders Available and/or design short-circuit current is an important consideration when de­ter­min­ing the class of fuse and fuse blocks to use. If available short-circuit current cannot be determined, or if it will vary with equip­ment location, select fuses with a 200,000 ampere interrupting rating (A.I.R.) and mating fuse blocks with a withstand rating of 200,000 amperes for maximum safety. 7. Determine if fuse clips need to be re­in­forced Fuse clips may have a tendency to lose some of their tension over a period of time. This may be prevented by specifying reinforced fuse clips. Reinforced clips are standard on certain fuse blocks (see individual product pages). Ordering Information The Littelfuse fuse block part number con­sists of 6 or 7 components, as shown below and in the individual fuse block data tables. 3. Determine the type and ampere rating of the fuse to be used In addition to voltage and interrupting rating as discussed above, the fuse ampere rating, opening characteristics (fast acting or time-delay) and size are other important con­sid­er­ations in fuse selection. Once the fuse type is selected, the mating fuse block can be chosen. Fuse blocks are available in 30, 60, 100, 200, 400 and 600 amp ratings, and may be used with a fuse rated at the cor­re­spond­ing amperage rating or below. For example, a fuse block rated at 30 amperes may be used with a fuse rated from 0 to 30 amperes. For all Class R, H, J, T and 15, 20 & 60A Class G Fuse Blocks © 2005 Littelfuse • POWR-GARD™ Products Catalog www.littelfuse.com For all Class CC, Midget and 30A Class G Fuse Blocks 111 Blocks and Holders Class T Fuse Blocks 300 and 600 Volt Features/Benefits Bases are molded phenolic. To provide a low resistance connection and long-range re­li­abil­i­ty, steel re­in­forc­ing springs are supplied as standard. Larger blocks employ an in­te­gral heat sink for maximum heat dissipation.
