Cooper Bussmann ATC-7-1/2 Automotive Fuse 7.5A 32V

Product Description

The COOPER BUSSMANN ATC-7-1/2 is a fast-acting automotive blade fuse rated at 7.5 amps and 32 volts DC. It is designed for overcurrent protection in automotive electrical systems and low-voltage control circuits. The housing is molded from polycarbonate for durability, while the terminal and element are zinc with a tin-plated finish for reliable conductivity. At 0.75 inches in overall length, this compact fuse fits standard ATC fuse holders found throughout light-duty vehicles, work trucks, and equipment wiring harnesses. Licensed electricians, automotive technicians, and equipment service techs install this fuse as a direct replacement when protecting 12V or 24V DC circuits.

The ATC-7-1/2 is suited for passenger vehicles, commercial trucks, off-road equipment, marine ignition-protected applications, and industrial low-voltage control panels. Its 7.5 amp rating makes it appropriate for accessory circuits, lighting circuits, and instrumentation loads that require fast response to fault conditions. This fuse is interchangeable with Littelfuse ATO07.5 and Ferraz Shawmut AF-7-1/2, making it a practical drop-in replacement during service calls without requiring holder modifications.

Compatibility

Cross-references to Littelfuse ATO07.5 and Ferraz Shawmut AF-7-1/2. Designed as an OEM-style replacement for standard ATC blade fuse holders used in automotive, marine, and low-voltage control circuit applications.

Installation Notes

Always disconnect the vehicle battery or de-energize the circuit before replacing a fuse. Verify the replacement fuse amperage matches the circuit protection requirement exactly — installing a higher-rated fuse can result in wiring damage or fire. ATC blade fuses are seated by hand into compatible holders; no tools are required for installation. For marine applications, confirm the holder and circuit meet SAE J1171 ignition protection requirements before installation.
