4-Pole 30A Automotive Fuse Block

The Bussmann 15600-04-20 is a four-pole fuse block designed for 32V DC automotive electrical systems. It accepts 3/4-inch blade-type fuses up to 30 amperes per circuit and mounts securely with a bolt-down base. The thermoplastic body meets UL 94VO flammability standards for safer installations.

Wire Range 16-12 AWG Output 6-4 AWG Input

This single specification determines fit: the block uses quick-connect terminals that accept 16 to 12 AWG wire on the output side and 6 to 4 AWG on the input side. Using wire outside these ranges will prevent a proper connection and can create a fire hazard in the vehicle.

Suits Installers Wiring Multiple Circuits on One

This block suits technicians consolidating up to four accessory circuits from a single heavy-gauge power feed. It is not for installers who need LED indication on each pole, require a rejection-style fuse holder to prevent wrong fuse insertion, or must fit the assembly into a space smaller than 1.84 by 3.37 by 0.8 inches.

Questions about this item

What does the 30 A rating mean when the block is installed in a 12 V vehicle system?

Each of the four poles can carry up to 30 A continuously at 32 V DC, so the block handles typical accessory circuits without overheating.

Which fuse series fit the 15600-04-20 and what is the maximum voltage they see?

The block accepts 257, AF and ATC series fuses measuring 3/4 in by 3/4 in by 13/64 in, all rated for 32 V DC maximum.

What mounting hardware and wire gauges are required for the bolt-down base?

The thermoplastic body mounts with bolts, takes 6 to 4 AWG input wires and 16 to 12 AWG output wires via quick-connect terminals.
