Cooper Bussmann ATC-3 Fast Acting Automotive Fuse 3A 32V

Product Description

The COOPER BUSSMANN ATC-3 is a fast-acting automotive blade fuse rated at 3 amps and 32 volts DC. It is designed to protect low-voltage automotive circuits and control wiring from overcurrent conditions. The fuse features a polycarbonate housing with zinc terminals and element, finished with tin plating for reliable contact. At 0.75 inches in overall length, it fits standard ATC-style fuse holders found throughout light-duty vehicles and low-voltage control panels. Licensed technicians and automotive electricians install this fuse during routine maintenance, circuit diagnostics, and control system service.

The ATC-3 is suited for automotive applications and low-voltage control circuits requiring fast-acting overcurrent protection at 3 amps. Typical installations include fuse blocks in passenger vehicles, light trucks, and auxiliary control systems. The fuse meets ISO 8820-3, SAE J1284, and JASO 612 standards, making it appropriate for OEM and aftermarket service across a wide range of 12-volt and 24-volt automotive electrical systems. Cross-reference equivalents listed in the input include Littelfuse ATO003 and Ferraz Shawmut AF-3.

Installation Notes

Installation and replacement of automotive fuses should be performed by a qualified automotive electrician or vehicle technician. Disconnect the vehicle battery or power source before accessing the fuse block to prevent arc flash or accidental circuit energization. Always replace with a fuse of the identical amperage rating — substituting a higher-rated fuse can cause wiring damage or fire. Verify the root cause of any blown fuse before restoring power to the circuit.
