Cooper Bussmann ATC-30 30A 32VDC Automotive Fuse

Product Description

The COOPER BUSSMANN ATC-30 is a fast-acting automotive blade fuse rated at 30 amps and 32 volts DC. It is designed for overcurrent protection in automotive electrical systems and low-voltage control circuits. The fuse features a polycarbonate housing with zinc terminals and element, finished in tin-plating for reliable contact. At 0.75 inches long with a standard ATC blade form factor, it installs directly into compatible fuse holders and fuse blocks found throughout light-duty vehicles and mobile equipment. Licensed electricians, automotive technicians, and electrical contractors working on 12-volt and 24-volt systems commonly specify this fuse for circuit protection applications.

The ATC-30 is suited for residential, commercial, and mobile equipment applications requiring fast-acting overcurrent protection at or below 32 volts DC. Typical installations include automotive fuse panels, marine electrical systems, RV power distribution blocks, and low-voltage control circuit boards. The ATC blade style is one of the most widely used automotive fuse formats in North American and international vehicle platforms. Cross-reference equivalents include the Littelfuse ATO030 and the Ferraz Shawmut AF-30.

Key Features

• 30 amp rating at 32 volts DC suits a wide range of accessory and control circuit loads
• Polycarbonate housing with tin-plated zinc terminals for corrosion resistance and secure seating
• Standard ATC blade form factor fits common automotive fuse holders and distribution blocks
• RoHS compliant and UL Recognized (File E56412, Guide JFHR2, UL 248-1)
• Meets ISO 8820-3, SAE J1284, JASO 612, and SAE J1171 ignition protection standards

Compatibility

Cross-references with Littelfuse ATO030 and Ferraz Shawmut AF-30. Designed for use in ATC-series blade fuse holders and fuse blocks rated for the ATC form factor in automotive and low-voltage DC control circuit applications.

Installation Notes

Installation is performed by automotive technicians or electricians servicing low-voltage DC systems. Disconnect the battery or de-energize the circuit before replacing any fuse. Verify that the replacement fuse amperage matches the circuit protection requirement — never substitute a higher-rated fuse to resolve a repeated blow condition without first diagnosing the underlying fault. Installations in marine environments should also comply with applicable ABYC standards for ignition-protected components.
