Cooper Bussmann AGC-2-1/2-R Fast-acting Cartridge Fuse 2.5A

Product Description

The COOPER BUSSMANN AGC-2-1/2-R is a glass-body cartridge fast-acting fuse rated at 2.5 amps. It is designed for overcurrent protection in low-amperage control circuits commonly found in HVAC equipment, appliances, and instrumentation panels. The fuse measures 1.25 inches in overall length and 0.25 inches in diameter, fitting standard AGC-style fuse holders. Its fast-acting response characteristic makes it suitable for circuits without high inrush current demands where immediate fault clearing is required. Licensed electricians and HVAC technicians install this fuse as a protective element in control boards, transformers, and low-voltage circuits. The glass body allows for quick visual confirmation of a blown fuse without removing it from the holder.

This fuse is used in residential and light commercial applications where AGC-series mini cartridge fuses are specified. Typical installation scenarios include HVAC control circuit protection, electronic equipment, and instrumentation where a 2.5A fast-acting fuse is required. The 0.25-inch diameter glass cartridge format is a widely used form factor across control panels and OEM equipment in the trade.

Key Features

• Fast-acting fuse timing for circuits without sustained inrush current
• Glass body construction allows visual inspection for blown-fuse confirmation
• Interrupting rating of 10,000A at 125V and 100A at 250V
• RoHS compliant and UL Listed (Guide JDYX File E19180)
• CSA certified and MIL-STD-202 tested for shock and vibration resistance
• Compact AGC mini cartridge form factor: 1.25 inches OAL, 0.25 inches diameter

Compatibility

Designed for use in standard AGC-style fuse holders accepting a 1.25-inch by 0.25-inch mini cartridge fuse rated at 2.5A fast-acting.

Installation Notes

Installation should be performed by a qualified electrician or HVAC technician following applicable NEC requirements. De-energize the circuit completely before replacing the fuse and verify the replacement amperage matches the circuit protection specification exactly. Do not substitute a higher-rated fuse to restore operation, as this defeats overcurrent protection. Inspect the fuse holder contacts for corrosion or damage during any fuse replacement service.
