Cooper Bussmann AGC-7-1/2-R Fast-acting Cartridge Fuse 7.5A

Product Description

The COOPER BUSSMANN AGC-7-1/2-R is a glass-body, cartridge-style fast-acting fuse rated at 7.5 amps. It measures 1.25 inches in overall length and 0.25 inches in diameter, making it a compact overcurrent protection device suited for control circuits, instrumentation, and low-voltage panel applications. The fast-acting response characteristic provides immediate interruption upon fault, protecting sensitive downstream components. With an interrupting rating of 10,000 amps at 125 volts and 200 amps at 250 volts, this fuse meets the demands of both residential and light commercial electrical service work. Licensed electricians and instrumentation technicians are the primary installers.

This fuse is commonly used in low-amperage control circuits, printed circuit board protection, instrumentation panels, and HVAC control applications where a standard AGC-style glass cartridge fuse is specified. Its mini-form factor fits standard fuse holders designed for 0.25-inch diameter cartridge fuses. The 7.5-amp rating targets circuits that require precise overcurrent protection without nuisance tripping under normal operating loads. It is appropriate for both residential and light commercial installations requiring UL-listed and CSA-certified components.

Compatibility

Designed as a direct-fit replacement for standard AGC-series glass cartridge fuse holders accepting 0.25-inch diameter by 1.25-inch length fast-acting fuses rated at 7.5 amps.

Installation Notes

Installation should be performed by a licensed electrician or qualified technician in accordance with NEC requirements for overcurrent protection. Always de-energize and lock out the circuit before replacing any fuse. Confirm the replacement fuse amperage and interrupting rating match the original specification before reinstalling. Do not substitute a higher-rated fuse to resolve a recurring blown-fuse condition without first diagnosing the underlying fault.
