Cooper Bussmann AGC-1/20 Cartridge Fast-acting Fuse 0.05A

Product Description

The COOPER BUSSMANN AGC-1/20 is a glass cartridge fast-acting fuse rated at 0.05 amps, designed for overcurrent protection in low-amperage electrical circuits. Measuring 1.25 inches in overall length and 0.25 inches in diameter, this mini-style fuse fits standard glass fuse holders commonly found in control panels, instrumentation, and light electrical equipment. The fast-acting design responds quickly to overload and short-circuit conditions, helping protect sensitive downstream components. It carries an interrupting rating of 10,000 amps at 125 volts and 35 amps at 250 volts, making it suitable for low-voltage control circuit applications. Licensed electricians and electronics technicians are the typical installers.

This fuse is used in residential and commercial control circuits, instrumentation panels, and electronic equipment where precise low-amperage protection is required. The 1/20-amp rating makes it appropriate for very low-current signal or control circuits. Its compact cartridge form factor allows direct installation into standard inline or panel-mounted fuse holders designed for the AGC mini glass fuse series. The glass body allows visual inspection for a blown element without removing the fuse from its holder.

Compatibility

Designed as an OEM-style replacement fuse for standard AGC-series glass cartridge fuse holders rated for mini 1.25-inch by 0.25-inch fuses in low-voltage control and instrumentation circuits.

Installation Notes

Installation should be performed by a qualified electrician or instrumentation technician. Always de-energize and lockout the circuit before replacing a fuse. Verify the replacement fuse amperage rating matches the circuit protection requirements exactly — substituting a higher-rated fuse can damage equipment or create a fire hazard. Refer to NEC guidelines for overcurrent protection requirements applicable to the circuit being serviced.
