Cooper Bussmann MAX-50 Fast Acting Maxi Blade Fuse 50A

Product Description

The COOPER BUSSMANN MAX-50 is a fast-acting maxi blade automotive fuse rated at 50 amps and 32 volts DC. Designed for high-current automotive and mobile equipment circuits, it provides reliable overcurrent protection with a fast-blow response that helps prevent wiring damage from short circuits and overloads. The zinc element construction and standard maxi blade form factor make it a direct replacement in fuse block positions requiring a 50-amp maxi fuse. The overall length is 1.35 inches and the overall width is 0.35 inches. This fuse is sold individually and is appropriate for fleet technicians, auto electricians, and mobile equipment service professionals.

This fuse is suited for automotive, fleet, marine, and light-duty commercial vehicle electrical systems where a maxi blade fuse block is installed. Typical applications include high-current feed circuits for accessories, power distribution centers, and main circuit protection in 12-volt and 24-volt DC systems. Compatible cross-references noted in product data include the Littelfuse MAX50 and Ferraz Shawmut AF3-50, making it a recognized equivalent in multi-brand service environments.

Installation Notes

Installation and replacement should be performed by a qualified auto electrician or fleet technician. Always disconnect the vehicle battery or de-energize the circuit before removing or installing a fuse. Verify the replacement fuse amperage matches the circuit requirement exactly — never substitute a higher-rated fuse to resolve a recurring blown fuse condition. Identify and correct the underlying fault before returning the circuit to service.
