Cooper Bussmann ATC-25 Fast Acting Automotive Fuse 25A

Product Description

The COOPER BUSSMANN ATC-25 is a fast-acting automotive blade fuse rated at 25 amps and 32 volts DC. It is designed to protect low-voltage wiring and control circuits in automotive and light-equipment electrical systems. The fuse features a polycarbonate housing with zinc terminals and element, finished with tin plating for reliable contact. At 0.75 inches in length, it fits the standard ATC blade fuse footprint found across a wide range of vehicles and equipment. Licensed electricians, automotive technicians, and low-voltage control installers use this fuse for circuit protection in both OEM and service applications.

The ATC-25 is suited for automotive wiring harnesses, ignition-protected systems, and low-voltage control circuits where a fast-acting response to overcurrent events is required. Its ATC series form factor makes it a direct replacement in standard blade fuse holders used in passenger vehicles, light trucks, marine applications, and mobile equipment. Cross-reference part numbers include Littelfuse ATO025 and Ferraz Shawmut AF-25.

Key Features

• 25-amp fast-acting response protects circuits against overcurrent damage
• Rated 32 volts DC for automotive and low-voltage control applications
• Polycarbonate housing with zinc terminal and element construction
• Tin-plated finish for secure, corrosion-resistant blade contact
• Meets ISO 8820-3, SAE J1284, JASO 612, and SAE J1171 ignition-protection standards
• UL Recognized under File E56412, Guide JFHR2, UL 248-1; RoHS compliant

Compatibility

Designed as a direct-fit replacement in standard ATC blade fuse holders. Cross-references to Littelfuse ATO025 and Ferraz Shawmut AF-25. Suitable for automotive wiring harnesses and low-voltage control circuits requiring a 25-amp, 32-volt DC fast-acting fuse.

Installation Notes

Disconnect the vehicle battery or de-energize the low-voltage control circuit before replacing any fuse. Verify the replacement fuse amperage matches the circuit requirements before installation — never substitute a higher-rated fuse to resolve a repeated blow condition without diagnosing the underlying fault. Use a fuse puller tool to avoid blade damage or terminal contact contamination. Marine and ignition-protected applications should confirm SAE J1171 compliance requirements are met.
