Cooper Bussmann GBB-10-R Cartridge Fast-acting Fuse 10A

Product Description

The COOPER BUSSMANN GBB-10-R is a ceramic cartridge fast-acting fuse rated at 10 amps, designed for overcurrent protection in low-voltage circuits. Measuring 1.25 inches in overall length and 0.25 inches in diameter, this compact fuse fits standard cartridge fuse holders in control panels, HVAC equipment, and electronic assemblies. The ceramic body provides reliable arc containment, and the fast-acting response ensures rapid interruption upon overcurrent events. With an interrupting rating of 10,000 amps at 125 volts and 200 amps at 250 volts, it is suitable for circuits where quick, decisive protection is required. Licensed electricians and HVAC technicians are the primary installers.

This fuse is used in residential and light commercial applications where a 10-amp, fast-acting cartridge fuse is specified. Common installation locations include low-voltage control circuit boards, transformer secondary circuits, HVAC control panels, and electronic equipment requiring miniature cartridge fuse protection. The mini cartridge form factor fits a wide range of panel-mount and inline fuse holders that accept 0.25-inch diameter cartridge fuses. It is sold in a minimum order quantity of 5 units.

Key Features

• Fast-acting response for rapid overcurrent interruption in sensitive circuits

Compatibility

Designed as a direct-fit replacement for standard 0.25-inch diameter by 1.25-inch mini cartridge fuse holders rated for fast-acting 10-amp protection in control circuit and electronic equipment applications.

Installation Notes

Always de-energize and lock out the circuit before replacing a fuse. Use a fuse puller rated for the holder size to avoid contact with live terminals and to prevent damage to the fuse body. Verify the replacement fuse amperage, voltage rating, and time-delay classification match the original specification before reinstallation. Installation should comply with applicable NEC requirements for overcurrent protection device selection and replacement.
