Cooper Bussmann AGC-20-R Cartridge Fast-acting Fuse 20A

Product Description

The COOPER BUSSMANN AGC-20-R is a glass-body, cartridge-style fast-acting fuse rated at 20 amps. It measures 1.25 inches in overall length and 0.25 inches in diameter, fitting the standard AGC mini fuse footprint used across a wide range of low-current protection applications. The fast-acting response characteristic means the fuse interrupts fault current quickly with minimal time delay, making it appropriate for protecting sensitive equipment and instrumentation. Electricians and electronics technicians install this fuse as an overcurrent protection device in control panels, small appliances, HVAC control circuits, and general-purpose equipment. The glass body allows visual inspection of the element without removal.

The AGC-20-R is suited for residential and light commercial applications where a 1/4-inch by 1-1/4-inch fast-acting fuse is specified. Common install scenarios include HVAC equipment control boards, small motor control circuits, instrumentation panels, and other low-voltage or low-current circuits requiring reliable overcurrent protection. The AGC fuse block form factor is widely used in OEM equipment across HVAC, electrical, and industrial controls.

Key Features

• Fast-acting fuse element for rapid fault interruption with no intentional time delay
• Glass cartridge body allows visual element inspection without fuse removal
• 20-amp rating suitable for light-duty overcurrent protection in control circuits
• Standard AGC mini footprint: 1.25 inches OAL by 0.25 inches diameter
• RoHS compliant construction
• UL Recognized and CSA Certified to multiple standards

Compatibility

Designed as a direct-fit replacement for any application specifying a 1/4-inch by 1-1/4-inch AGC-style fast-acting cartridge fuse at 20 amps. Compatible with standard AGC fuse holders and fuse blocks accepting this footprint.

Installation Notes

This fuse is installed by qualified electricians or electronics technicians following applicable NEC guidelines for overcurrent protection. Always de-energize and lock out the circuit before replacing a fuse. Confirm the replacement fuse amperage and fuse timing match the original equipment specification exactly — substituting a higher-rated or slow-blow fuse can leave equipment unprotected. Use a fuse puller or appropriate tool when removing the fuse from a cartridge fuse holder to avoid contact with live terminals.
