Cooper Bussmann GMC-5-R Cartridge Time Delay Fuse 5A

Product Description

The COOPER BUSSMANN GMC-5-R is a glass-body, cartridge-style time delay fuse rated at 5 amps and 10 kiloamps (kA) interrupting capacity at AC. Built in the international 20 mm x 5 mm mini form factor, it provides overcurrent protection with a time delay characteristic that tolerates brief inrush currents without nuisance opening. The glass body allows visual inspection of the fuse element without removal. Licensed electricians and electronics technicians install this fuse in control panels, instrumentation circuits, and low-voltage equipment where a compact, standards-certified overcurrent device is required.

The GMC-5-R fits the 5 x 20 mm fuse format common in European-style control panels, small appliances, instrumentation, and industrial equipment. Its time delay (slow-blow) rating suits circuits with motor loads or capacitive inrush that would open a fast-acting fuse at startup. The 5-amp rating and compact cartridge body make it a standard choice in low-voltage AC and DC control circuits across light commercial and residential applications.

Key Features

• Time delay (slow-blow) characteristic tolerates startup inrush without nuisance trips
• 10 kA interrupting rating at AC for reliable fault protection
• Glass body allows visual fuse-element inspection in the field
• 5 x 20 mm mini cartridge form factor fits standard international fuse holders
• UL Listed, CSA Certified, KC-Mark Certified, and RoHS Compliant

Compatibility

Designed as an OEM-style replacement for 5 x 20 mm mini cartridge time delay fuse positions in control panels, instrumentation enclosures, and low-voltage equipment requiring a 5-amp slow-blow fuse.

Installation Notes

Fuse replacement should be performed by a qualified electrician or electronics technician with the circuit de-energized and capacitors discharged before service. Always verify the replacement fuse matches the original amperage rating, fuse timing, and body dimensions before installing. Never substitute a fast-acting fuse for a time delay type in a circuit designed for slow-blow protection. Refer to the equipment manufacturer's service documentation and applicable NEC requirements for fusing guidelines.
