Cooper Bussmann ATC-35 Fast Acting Automotive Fuse 35A

Product Description

The COOPER BUSSMANN ATC-35 is a fast-acting automotive blade fuse rated at 35 amps and 32 volts DC. It is designed for overcurrent protection in automotive electrical systems and low-voltage control circuits where rapid response to fault conditions is required. The housing is molded from polycarbonate, and the terminal and element are constructed from tin-plated zinc. At 0.75 inches in overall length, it fits the standard ATC blade fuse footprint found throughout light-duty vehicle and equipment wiring harnesses. Licensed electricians and automotive technicians install this fuse type as part of OEM and aftermarket fuse panel service.

This fuse is suited for passenger vehicles, light trucks, powersports equipment, marine ignition-protected systems, and low-voltage control panels operating at or below 32 volts DC. It carries ratings under ISO 8820-3, SAE J1284, JASO 612, and SAE J1171 for ignition protection, making it appropriate for both road vehicle and marine applications. It is also UL Recognized under File E56412, Guide JFHR2, and UL 248-1 for fuses in the 1-40 amp range. Replacement cross-references listed in the source data include Littelfuse ATO035 and Ferraz Shawmut AF-35.

Key Features

• Fast-acting response provides immediate overcurrent interruption to protect vehicle wiring and components
• 35 amp rating at 32 volts DC suits high-draw automotive accessory circuits
• Polycarbonate housing with tin-plated zinc terminals for corrosion resistance in under-hood environments
• Standard ATC blade fuse form factor for direct plug-in installation
• Meets ISO 8820-3, SAE J1284, JASO 612, SAE J1171, and UL 248-1 requirements
• RoHS compliant

Compatibility

Designed as a direct replacement for Littelfuse ATO035 and Ferraz Shawmut AF-35. Fits standard ATC-style blade fuse holders used in automotive, marine, and low-voltage control circuit applications rated up to 32 volts DC.

Installation Notes

Installation is performed by automotive technicians or qualified electricians servicing vehicle fuse panels or low-voltage control enclosures. Always disconnect the battery or de-energize the circuit before replacing a fuse. Verify the replacement fuse amperage matches the circuit protection requirement exactly — never substitute a higher-rated fuse to address a repeated blow condition without first diagnosing the underlying fault. Marine installations must confirm ignition-protection compliance per SAE J1171 before use near fuel systems.
