Cooper Bussmann MAX-80 Fast Acting Maxi Fuse 80A 32V

Product Description

The COOPER BUSSMANN MAX-80 is a fast-acting maxi blade automotive fuse rated at 80 amps and 32 volts DC. It protects automotive electrical circuits from overcurrent conditions by opening quickly when current exceeds the rated threshold. The zinc element construction provides reliable, consistent response characteristics. At 1.35 inches long and 0.35 inches wide, this fuse fits standard maxi blade fuse holders and power distribution blocks used in 12-volt and 24-volt DC vehicle and equipment wiring systems. Automotive electricians and fleet maintenance technicians install this fuse as a primary circuit protection device.

The MAX-80 is designed for automotive and mobile equipment applications where high-current circuit protection is required. Typical installations include main power feeds, heavy accessory circuits, and battery-side protection in passenger vehicles, commercial trucks, trailers, and off-road equipment. Its maxi blade form factor is widely used in underhood fuse blocks and aftermarket power distribution modules. This fuse is also sold under cross-reference part numbers Littelfuse MAX80 and Ferraz Shawmut AF3-80, making it a recognized replacement option across multiple brands.

Installation Notes

Installation should be performed by a qualified automotive electrician or experienced technician. Disconnect the battery or de-energize the circuit before replacing any fuse. Confirm the replacement fuse amperage matches the circuit protection requirement exactly — never substitute a higher-rated fuse. Verify the fuse holder is clean and free of corrosion before seating the new fuse.
