Cooper Bussmann ABC-3-R Cartridge Fast-acting Fuse 3A

Product Description

The COOPER BUSSMANN ABC-3-R is a ceramic cartridge fast-acting fuse rated at 3 amps. Measuring 1.25 inches in overall length and 0.25 inches in diameter, this miniature fuse is designed for overcurrent protection in control circuits, instrumentation, and light electrical equipment. Its fast-acting response trips quickly on overload, protecting sensitive downstream components from sustained fault current. The ceramic body provides strong resistance to heat and arc energy. Licensed electricians, controls technicians, and electronics service pros install this fuse in panel boards, junction boxes, and equipment enclosures where compact, reliable overcurrent protection is required.

The ABC-3-R is suited for residential and light commercial control circuits operating at up to 250 volts AC. Its compact 1.25-inch cartridge form factor fits standard miniature fuse holders and fuseholders commonly found in HVAC control boards, instrumentation panels, and low-voltage equipment. The 3-amp rating and fast-acting timing make it appropriate for protecting transformer secondaries, control wiring, and electronic loads where fast fault clearance is critical.

Installation Notes

Installation should be performed by a licensed electrician or qualified controls technician in accordance with NEC requirements. De-energize and lock out the circuit before removing or installing any fuse. Confirm the replacement fuse amperage and voltage rating match the original fuse and the requirements of the protected circuit. Never install a fuse with a higher amperage rating than specified by the equipment manufacturer.
