Space-saving 600 volt, 30 amp molded-case fuse blocks with side barriers for isolation. Long Life: High-strength materials — 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, one-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 — 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. Additional Features: DIN rail mountable — FBDIN1 adapters permit snap-mounting Littelfuse Midget fuse blocks directly to standard or low profile 35mm symmetrical "hat" and 32mm asymmetrical DIN rails. Patented DIN rail adapters snap securely to Littelfuse fuse blocks and to DIN rails without tools. They can be readily removed from rails by lifting the disconnect tab.
