The Bussmann BBS-4 is a 4-amp, fast-acting midget glass cartridge fuse designed for automotive and general electrical protection. It features ferrule-end nickel-plated brass endcaps and a 10 kA interrupting rating at up to 600 V, with dimensions of 13/32 in diameter by 1-3/8 in long (10.4 mm x 35 mm). This non-indicating fuse uses standard Bussmann cartridge construction, and is commonly specified for control circuits, lighting ballasts, and meter circuits where quick protection against overcurrent is needed. It is widely used in automotive and other circuits requiring a 4 A fuse in a 1-3/8 inch glass cartridge format.
