Cooper Bussmann AGC-12-R Cartridge Fast-acting Fuse 12A

Product Description

The COOPER BUSSMANN AGC-12-R is a glass cartridge fast-acting fuse rated at 12 amps. It is designed for overcurrent protection in low-voltage control circuits, instrumentation panels, and general-purpose electrical applications. The AGC-12-R measures 1.25 inches in overall length and 0.25 inches in diameter, making it a standard mini cartridge form factor. Its fast-acting response means it opens quickly on overload or short-circuit conditions without an intentional time delay. Electricians, electronics technicians, and HVAC controls technicians install this type of fuse as a protective element in fuse holders and fuse blocks across a wide range of control and signal circuits.

The AGC-12-R is suited for residential and commercial applications where a mini glass cartridge fuse is specified. Typical installations include low-voltage control panels, HVAC control boards, instrumentation enclosures, small motor circuits, and electronic equipment requiring fast overcurrent response. The glass body allows for visual inspection of the fuse element without removal, which speeds up troubleshooting during service calls.

Key Features

• Glass body construction enables visual inspection of fuse element
• Compact mini cartridge form factor: 1.25 inches OAL, 0.25 inches diameter
• RoHS compliant construction
• UL Recognized under Guide JDYX2 File E19180
• CSA certified and MIL-STD-202 tested for shock and vibration durability

Compatibility

Designed as an OEM-style replacement for standard AGC-series mini glass cartridge fuse applications requiring a fast-acting 12-amp, 0.25-inch diameter fuse in compatible fuse holders and fuse blocks.

Installation Notes

Installation should be performed by a qualified electrician or licensed technician. Always de-energize and lock out the circuit before replacing a fuse. Verify the replacement fuse amperage and form factor match the original specification before inserting into the fuse holder. Never substitute a higher-amperage fuse to bypass a repeated overcurrent condition — diagnose the root cause first.
