Cooper Bussmann AGC-5-R Fast-acting Cartridge Fuse 5A

Product Description

The COOPER BUSSMANN AGC-5-R is a fast-acting glass cartridge fuse rated at 5 amps and designed for overcurrent protection in low-voltage control circuits, instrumentation panels, and electronic equipment. The glass body allows visual inspection of the fuse element without removal. It carries an interrupting rating of 10,000 amps at 125 volts and 200 amps at 250 volts, making it suitable for applications where fault current levels must be carefully matched to fuse capacity. Licensed electricians and electronics technicians install this fuse in control panels, HVAC equipment, and test instrumentation where fast-acting protection is required.

This fuse is commonly used in residential and light commercial HVAC control circuits, laboratory instruments, and industrial control panels. It is a standard AGC-style glass cartridge fuse, a format widely used across OEM equipment in the trade. The compact 1.25-inch overall length and 0.25-inch diameter allow it to fit standard fuse clips and inline fuse holders designed for this body style. Typical applications include transformer secondary protection, low-current branch circuit protection, and printed circuit board fuse positions.

Key Features

• Fast-acting fuse response for protection of sensitive electronic components and control circuits
• Glass body enables visual inspection of fuse element without a continuity tester
• 10,000-amp interrupting rating at 125 volts for high fault-current environments
• Meets CSA, UL, MIL-STD-202, and RoHS compliance requirements
• Standard AGC cartridge form factor fits widely available fuse clips and holders

Compatibility

Designed as a direct-fit replacement for standard AGC-style glass cartridge fuse positions rated for 5 amps in control panels, instrumentation, and HVAC equipment using 1.25-inch by 0.25-inch fuse holders.

Installation Notes

Always de-energize and lockout the circuit before replacing a fuse. Confirm the replacement fuse amperage and voltage rating match the circuit requirements exactly — never substitute a higher-rated fuse. Use an appropriate fuse puller when removing cartridge fuses from live-rated holders to avoid contact with energized terminals. Installation should comply with NEC requirements for overcurrent protection devices as applicable to the equipment being serviced.
