Space-saving 600 V, 30 A molded case fuse blocks with side barriers for isolation. Class CC blocks and midget blocks are identical except class CC blocks incorporate a rejection feature to assure Proper fusing. Safety : rejection feature class CC fuse blocks have a rejection feature which prevents the insertion of fuses with lower interrupting rating or voltage ratings. Class CC fuses are rated 600 V and have an interrupting rating of 200000 A. Midget fuse voltage ratings vary and their interrupting rating may be as low as 10000 A. Note that class CC fuses may be used in midget fuse blocks, but midget fuses cannot be used in class CC blocks. Long Life: high-strength materials class CC and midget fuse blocks are molded of high-strength, high temperature material to minimize block breakage during handling and installation, as well as damage due to heat. Reduced resistance, less heat high conductivity, 1-piece copper alloy fuse clips have lower resistance than traditional two-piece brass or phosphor bronze fuse clips minimizes heat rise and watts loss within the fuse block. Reduced inVentory: Gangable interlocking fuse blocks allow ganging to produce a fuse block with any number of poles. Flexible terminal arrangements 30 A class CC and midget fuse blocks are available with type C box lug, type SQ screw or type PQ pressure plate terminals. Type SQ terminals have binding head screws, while type PQ terminals have captive pressure plates. Both terminal types can accommodate side or top mounted quick connect terminals. This flexibility allows the accommodation of most needs and reduces part inVentory requirements.
