With a light-blue body, visual inspection window, and a 10,000 AIC interrupt rating at 14V DC, the 5176 meets ABYC requirements for protecting main DC circuits on larger battery banks. It’s intended for use with the matching terminal fuse blocks rather than direct battery mounting, giving installers a safer, code-compliant method to add overcurrent protection.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the terminal fuse protect my battery bank?\u003c\/h3\u003e\n\u003cp\u003eThe 5176 interrupts excessive current before wiring or connected equipment sustain damage, thanks to a high interrupt rating and reliable fuse element.
