Cooper Bussmann ATC-5 Fast Acting Automotive Fuse 5A

Product Description

The COOPER BUSSMANN ATC-5 is a fast-acting automotive blade fuse rated at 5 amps and 32 volts DC. It is designed for overcurrent protection in automotive electrical systems and low-voltage control circuits. The fuse housing is constructed from polycarbonate, with zinc terminals and a tin-plated element for reliable conductivity. At 0.75 inches in length, it fits standard ATC blade fuse holders found throughout light-duty vehicles and equipment. Licensed HVAC techs, auto electricians, and equipment technicians install this fuse during routine service or fault diagnosis on 12-volt and 24-volt systems.

The ATC-5 is suited for automotive wiring harnesses, accessory circuits, control panel protection, and low-voltage equipment applications. Its fast-acting response provides immediate interruption when an overcurrent event occurs, helping protect downstream components and wiring. It is applicable in both passenger vehicles and equipment with low-voltage control circuits requiring ATC-style fuse protection.

Key Features

• Fast-acting fuse element interrupts overcurrent events quickly to protect downstream wiring and components
• Polycarbonate housing with zinc terminal and element construction for durability
• Tin-plated terminals for corrosion resistance and consistent contact
• Compact 0.75-inch length fits standard ATC blade fuse holders
• Meets ISO 8820-3, SAE J1284, JASO 612, and UL 248-1 standards
• RoHS compliant and UL Recognized (File E56412, Guide JFHR2)

Compatibility

The ATC-5 is a direct cross-reference replacement for Littlefuse ATO005 and Ferraz Shawmut AF-5 PK5. It is designed for any application requiring an ATC-series 5-amp blade fuse in 32 VDC or lower circuits.

Installation Notes

Automotive fuse replacement should be performed with the ignition off and all accessory loads de-energized before servicing the fuse block. Use a fuse puller tool to remove and seat the fuse cleanly without damaging adjacent circuits. Always replace with a fuse of identical amperage rating — never substitute a higher-rated fuse. This fuse does not include a blown fuse indicator, so visual inspection of the element or continuity testing is required to confirm an open circuit.
