Cooper Bussmann AGX-1/4 Fast-acting Cartridge Fuse 0.25A

Product Description

The COOPER BUSSMANN AGX-1/4 is a glass-body, mini cartridge fast-acting fuse rated at 0.25 amps and designed for low-current circuit protection in control panels, instruments, and light electrical equipment. Measuring 1 inch overall length with a 0.25-inch diameter, this fuse opens rapidly on overcurrent events to protect sensitive downstream components. The glass body allows visual confirmation of a blown fuse without removing it from the holder. It carries an interrupting rating of 10,000 amps at 125 volts and 35 amps at 250 volts, making it appropriate for standard low-voltage control circuits. Electricians and control-panel technicians are the typical installers.

This fuse suits residential and light commercial applications where small-signal or low-power circuits require fast overcurrent protection. Common installation locations include instrumentation panels, HVAC control boards, small appliance circuits, and electronic equipment requiring IEC-style glass cartridge fuse holders. The AGX series is a widely recognized format in both OEM assemblies and field-replacement scenarios. Its fast-acting response time makes it unsuitable for motor-starting or inductive-load circuits where a time-delay fuse would be required.

Key Features

• Fast-acting response for immediate overcurrent protection on resistive and sensitive electronic loads
• Glass fuse body allows quick visual inspection for blown-fuse diagnosis without a meter
• 10,000-amp interrupting rating at 125 volts for reliable fault clearing
• Mini cartridge form factor fits standard AGX-series fuse holders and clips
• cULus Recognized and UL Listed 248-14 for code-compliant installations

Compatibility

Designed as an OEM-style replacement for standard mini glass cartridge fuse holders accepting a 1-inch by 0.25-inch AGX-format fuse.

Installation Notes

Installation is performed by a qualified electrician or control-panel technician. Always de-energize and lock out the circuit before replacing a fuse. Verify that the replacement fuse matches the amperage, voltage, and time-delay rating specified on the equipment nameplate or wiring diagram. Do not install a higher-rated fuse than specified, as this defeats overcurrent protection.
