Product Overview

A four circuit fuse block that will fit almost anywhere

Fuse Blocks are an effective method of protection to prevent damage to wiring and possible fire in the event of an over-loaded or short circuit. This Blue Sea Systems space-saving fuse block can provide protection for new installations or when the panel has run out of breakers. Often used for electronic installations, these fuse blocks can be fed by one breaker from the distribution panel and supply power to 4 additional circuits. Terminals are located on one side to concentrate wiring and minimize the overall footprint of the fuse block. A clear cover insulates fuses and terminals from accidental contact and satisfy ABYC and USCG requirements.
