Cooper Bussmann ATC-1 Fast Acting Automotive Fuse 1A

Product Description

The COOPER BUSSMANN ATC-1 is a fast-acting automotive blade fuse rated at 1 amp and 32 volts DC. It is designed for use in automotive electrical systems and low-voltage control circuits where quick overcurrent protection is required. The fuse features a polycarbonate housing with tin-plated zinc terminals and element, conforming to the standard ATC blade format. At 0.75 inches in length, it fits directly into standard ATC fuse holders and fuse blocks. Installation is performed by automotive technicians and low-voltage electrical specialists working on vehicle or equipment control wiring.

This fuse is suited for automotive applications and low-voltage control circuits operating at up to 32 volts DC. It meets ISO 8820-3, SAE J1284, and JASO 612 standards covering the 1 to 40 amp ATC series range, making it appropriate for use in passenger vehicles, light trucks, and similar equipment requiring blade-style fuse protection. It also carries SAE J1171 ignition protection rating and UL Recognized status under File E56412, Guide JFHR2, and UL 248-1.

Installation Notes

Installation is performed by qualified automotive technicians or low-voltage electrical technicians. Disconnect or isolate the circuit before removing or installing the fuse to prevent arcing or accidental short circuits. Confirm the replacement fuse amperage matches the circuit rating exactly — never substitute a higher-amperage fuse. Fuse pullers are recommended over bare-hand removal to avoid terminal damage.
