Cooper Bussmann AGX-25 Cartridge Fast-acting Fuse 25A

Product Description

The COOPER BUSSMANN AGX-25 is a glass-body, mini cartridge fast-acting fuse rated at 25 amps. It measures 1 inch in overall length and 0.25 inches in diameter, fitting the standard AGX miniature fuse form factor. Fast-acting fuses open the circuit nearly instantaneously on overload, making them the correct choice for protecting sensitive electronic components and low-inrush loads where a time-delay element would allow damaging current to pass. Licensed electricians and electronics technicians install this fuse type in control panels, instrumentation circuits, and low-voltage protection applications.

The AGX-25 is suited for residential and light commercial control circuits, small appliance protection, and electronic equipment where a compact 1/4-inch diameter cartridge fuse is specified. It is commonly found in HVAC control board fuse holders, low-voltage wiring panels, and test equipment requiring AGX-style glass cartridge fuses. The glass body allows visual inspection of the element without removing the fuse from its holder, which speeds up field diagnostics during service calls.

Key Features

• Fast-acting response for immediate overcurrent protection on sensitive circuits
• Glass body enables visual element inspection without fuse removal
• 25-amp rating at standard AGX miniature dimensions
• Interrupting rating of 100 amps at 125 volts and 1,000 amps at 32 volts
• UL Listed 248-14 and CSA Component Accepted for code-compliant installations
• Mini cartridge form factor fits standard AGX fuse clips and panel holders

Compatibility

Designed as an OEM-style replacement for AGX-series mini cartridge fuse holders and panels that accept a 1/4-inch diameter by 1-inch length fast-acting glass fuse.

Installation Notes

Disconnect or de-energize the circuit before replacing any fuse. Confirm the replacement fuse amperage and voltage rating match the application requirements exactly — installing a higher-rated fuse than specified can defeat overcurrent protection and create a fire hazard. Use an appropriately rated fuse puller when removing cartridge fuses from spring-clip holders. Follow applicable NEC guidelines for fuse selection and circuit protection in low-voltage control wiring.
