Product Overview

  • Add circuit protection at the battery without having to cut a wire

    Terminal fuse blocks provide circuit protection by attaching a fuse block directly to the battery terminal. Simply secure a single or double fuse block to the battery terminal, select the appropriate fuse, and attach conductors. Ideal for circuit protection when space is limited. Fuses are available from 30A to 300A to meet the circuit requirements. An integral cover fits over the terminal studs to prevent accidental terminal contact.
