Cooper Bussmann AGC-3/10-R Cartridge Fast-acting Fuse 0.3A

Product Description

The COOPER BUSSMANN AGC-3/10-R is a glass-body cartridge fast-acting fuse rated at 0.3 amps and designed for overcurrent protection in low-amperage circuits. Measuring 1.25 inches overall length with a 0.25 inch diameter, this miniature fuse interrupts fault current at up to 10,000 amps at 125 volts, providing reliable protection in sensitive electronic and control circuits. Its fast-acting timing ensures rapid response to overcurrent events, minimizing downstream damage. Electricians and control panel technicians install this fuse type in instrument panels, HVAC control boards, low-voltage circuits, and similar applications requiring precise overcurrent protection in a compact form factor.

The AGC-3/10-R is suited for use in residential and light commercial control circuits, instrument panels, and electronic equipment where a standard 1/4 inch by 1-1/4 inch miniature glass cartridge fuse is required. Its RoHS-compliant construction and multi-standard certifications make it appropriate for installations subject to UL, CSA, and military-standard compliance requirements. Technicians working on HVAC control boards, fire alarm systems, and low-voltage panel circuits will find this fuse size commonly specified across a wide range of OEM equipment.

Compatibility

Designed as an OEM-style replacement miniature glass cartridge fuse for any application requiring a 1/4 inch by 1-1/4 inch fast-acting fuse at 0.3 amp rating.

Installation Notes

Installation should be performed by a qualified electrician or control technician. Always de-energize and lock out the circuit before replacing any fuse. Verify the replacement fuse amperage rating matches the circuit protection requirements exactly — substituting a higher-rated fuse can damage equipment and create a safety hazard. NEC guidelines apply to fuse replacement in panel and control circuit applications.
