Cooper Bussmann AGC-3/8-R Fast-acting Cartridge Fuse 0.38A

Product Description

The COOPER BUSSMANN AGC-3/8-R is a glass-body cartridge fast-acting fuse rated at 0.38 amps. It measures 1-1/4 inches in overall length with a 1/4 inch diameter, conforming to the standard AGC miniature fuse form factor widely used in control circuits, instrumentation panels, and low-voltage protection applications. The fast-acting response characteristic means the fuse opens quickly on overloads with minimal delay, making it suitable for protecting sensitive electronic components and precision equipment. Licensed electricians and instrumentation technicians are the typical installers for this type of fuse.

This fuse is used in residential, commercial, and light industrial control panels, HVAC equipment control boards, and electronic instrumentation wherever a miniature AGC-style fuse holder is present. Its 0.38A rating targets low-current circuit protection needs. The glass body allows visual inspection of the fuse element without removal, which speeds up fault diagnosis during service calls. It is appropriate for circuits operating at up to 125 volts AC with an interrupting rating of 10,000 amps, or at up to 250 volts AC with an interrupting rating of 35 amps.

Key Features

• Fast-acting fuse response for protecting sensitive low-current electronic circuits
• Glass cartridge body allows visual inspection of the fuse element without removal
• 10,000A interrupting rating at 125V AC for reliable fault clearing
• Meets UL, CSA, MIL-STD-202, and RoHS requirements for broad application compliance
• Standard AGC miniature form factor fits common panel-mount and inline fuse holders
• Lightweight at approximately 0.01 pounds per unit

Compatibility

Designed as a direct-fit replacement for standard AGC-style miniature cartridge fuse holders rated for 1/4 inch diameter by 1-1/4 inch overall length fuses in control panels, HVAC equipment, and electronic instrumentation.

Installation Notes

Installation should be performed by a licensed electrician or qualified service technician in accordance with applicable NEC guidelines. Always de-energize and lock out the circuit before replacing fuses. Verify the replacement fuse amperage and voltage rating match the circuit requirements before inserting. Never substitute a higher-amperage fuse to bypass a repeated fuse failure — diagnose and correct the underlying fault first.
