Cooper Bussmann ABC-30-R Cartridge Fast-acting Fuse 30A

Product Description

The COOPER BUSSMANN ABC-30-R is a mini cartridge fast-acting fuse rated at 30 amps. It is designed for overcurrent protection in low-voltage electrical circuits where fast response to fault conditions is required. The ceramic fuse body measures 1.25 inches in overall length and 0.25 inches in diameter. Its fast-acting timing means it opens quickly under overload or short-circuit conditions, protecting downstream components. Licensed electricians and electronics technicians typically specify this fuse for control circuits, instrumentation panels, and light-duty electrical equipment requiring a compact, reliable overcurrent device.

This fuse is suited for use in residential and commercial control panels, HVAC equipment control circuits, instrumentation, and small appliance protection where a 1/4-inch by 1-1/4-inch mini cartridge form factor is required. The ceramic body construction provides thermal stability and arc containment. The interrupting rating of 1000 amps at 250/125 volts makes it appropriate for branch circuit protection applications within its rated current class. It ships individually but must be ordered in multiples of 5.

Compatibility

Designed as a direct-replacement mini cartridge fuse for 1/4-inch by 1-1/4-inch fuse holders and panels requiring a 30 amp fast-acting fuse in the ABC series form factor.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. Always de-energize and lock out the circuit before removing or installing a fuse. Verify that the replacement fuse amperage and voltage ratings match the circuit specifications before installation. Never substitute a fuse with a higher amperage rating than the circuit is designed to carry.
