Eaton Bussmann agc-20-r 3AG Fast-acting Glass Tube Fuse 20A

Product Description

The EATON BUSSMANN agc-20-r is a 3AG fast-acting glass tube fuse rated at 20 amps and 32 volts AC or 32 volts DC. It measures 0.25 inches in diameter by 1.25 inches in length, conforming to the standard 1/4 inch x 1-1/4 inch 3AG form factor. The fuse features a glass tube body with nickel-plated brass end caps and ferrule-to-ferrule connection. It carries a non-indicating design, meaning it provides no visible blown-fuse signal beyond physical inspection. Each package contains 5 fuses. Electricians and electronics technicians install these in control panels, instrumentation, and low-voltage electronic circuit applications.

This fuse is suited for electronic circuits requiring fast overcurrent protection at low voltages. The 3AG form factor is widely used in residential and light commercial control boards, test equipment, audio equipment, and other electronic assemblies. The fast-acting response characteristic makes it appropriate for circuits without high inrush current loads. It is sold in a 5-pack, which is practical for service technicians stocking replacement fuses for routine maintenance or repair calls.

Key Features

• 20A amperage rating with fast-acting response: 60 minutes at 135 percent load, 120 seconds at 200 percent load
• Rated 32 volts AC and 32 volts DC (self-certified)
• Interrupt rating of 1 kAIC at 32 volts AC
• Standard 1/4 inch x 1-1/4 inch 3AG glass tube form factor
• Nickel-plated brass end caps with ferrule-end connection
• RoHS Compliant and CE Marked
• Quantity of 5 fuses per pack

Compatibility

Designed as an OEM-style replacement for standard 3AG fast-acting glass tube fuse positions in electronic circuits and low-voltage control applications without axial leads.

Installation Notes

Installation should be performed by a qualified electrician or electronics technician. Always de-energize and verify the circuit is at zero voltage before removing or installing a fuse. Confirm that the replacement fuse amperage and voltage ratings match the circuit protection requirements exactly. Do not substitute a higher-rated fuse to resolve nuisance tripping, as this may indicate an underlying fault that requires diagnosis.
