The COOPER BUSSMANN AGC-4-R is a glass cartridge fast-acting fuse rated at 4 amps, designed for overcurrent protection in low-voltage electrical circuits. Measuring 1.25 inches in overall length and 0.25 inches in diameter, this miniature fuse fits standard AGC-style fuse holders commonly found in control panels, instrumentation, and light-duty electrical equipment. With an interrupting rating of 10,000 amps at 125 volts and 200 amps at 250 volts, it provides reliable fault clearing across a range of circuit protection applications. The glass body allows for quick visual inspection of the fuse element without removing the fuse from the holder.
This fuse is suited for residential, commercial, and light industrial electrical applications where fast-acting overcurrent protection is required. Typical install scenarios include control panel wiring, low-voltage instrumentation circuits, HVAC control boards, and similar equipment requiring a miniature cartridge fuse. Electricians and electronics technicians are the primary installers. The AGC-4-R meets multiple industry standards and is appropriate wherever an AGC-style 4-amp fast-acting fuse is specified.
Designed as an OEM-style replacement for standard AGC-style miniature cartridge fuse holders rated for 4-amp fast-acting fuses in low-voltage control and instrumentation circuits.
Installation should be performed by a qualified electrician or instrumentation technician. Always de-energize and lock out the circuit before replacing a fuse. Confirm the replacement fuse matches the amperage and voltage rating specified for the circuit. Do not substitute a higher-amperage fuse to restore operation — identify and correct the root fault first.
