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

Product Description

The COOPER BUSSMANN AGC-3-R is a glass cartridge fast-acting fuse rated at 3 amps. It measures 1.25 inches in overall length and 0.25 inches in diameter, making it a standard AGC-style miniature fuse used across a wide range of low-current electrical protection applications. The fast-acting timing characteristic means it responds immediately to overcurrent conditions without intentional delay, protecting sensitive components from damage. Licensed electricians and electronics technicians install this fuse in control panels, instrumentation circuits, HVAC control boards, and other equipment requiring compact, reliable overcurrent protection.

This fuse is suited for residential and light commercial applications where a glass-body AGC miniature fuse is specified. Typical installations include HVAC equipment control circuits, small appliances, test instruments, and electronic control panels. Its compact form factor fits standard AGC fuse holders and fuse clips commonly found in this equipment. The glass body allows visual inspection of the fuse element without removal from the circuit.

Key Features

Compatibility

Designed as a direct-fit replacement for standard AGC-style miniature cartridge fuse holders and fuse clips requiring a 0.25-inch diameter by 1.25-inch overall length fast-acting fuse rated at 3 amps.

Installation Notes

Always de-energize the circuit and verify absence of voltage before replacing a fuse. Use an appropriately rated fuse puller when removing cartridge fuses from spring-clip holders to avoid contact with live terminals. Confirm the replacement fuse amperage and voltage rating match the equipment nameplate or wiring diagram before installation. Recurring fuse failures indicate an underlying fault that must be diagnosed before returning the circuit to service.
