Cooper Bussmann GMD-1.6-R Cartridge Time Delay Fuse

Product Description

The COOPER BUSSMANN GMD-1.6-R is a miniature cartridge time delay fuse rated at 1.6 amps. It is designed for overcurrent protection in low-current electronic circuits, control panels, and instrumentation equipment. The glass body measures 20 mm in overall length and 5 mm in diameter, conforming to the standard IEC 5x20 mm fuse form factor. The time delay characteristic allows brief inrush current surges to pass without nuisance opening, while still protecting the circuit against sustained overloads. Licensed electricians and electronics technicians install this fuse type in a wide range of control and signal-level applications.

This fuse is suited for residential and commercial control circuits, printed circuit board fuse holders, and panel-mount fuse blocks that accept the 5x20 mm cartridge format. Its glass construction allows visual inspection of the fuse element without removal. The interrupting rating of 10,000 amps at 125 volts and 100 amps at 250 volts makes it appropriate for low-voltage control circuit protection where high fault-current interruption is required at the lower voltage range.

Key Features

• Time delay (slow-blow) fuse element tolerates short-duration inrush currents without nuisance tripping
• 1.6 amp rating for precise low-current circuit protection
• Standard 5x20 mm IEC cartridge form factor fits common panel and PCB fuse holders
• Glass body enables quick visual inspection of fuse element condition
• Interrupting rating of 10,000 amps at 125 volts for robust fault protection at low voltage
• Meets multiple certifications including UL, CSA, PSE/JET, and RoHS compliance

Compatibility

Designed for use in standard 5x20 mm cartridge fuse holders used in low-voltage electronic control panels, instrumentation, and signal-level circuits requiring a time delay fuse element.

Installation Notes

Installation should be performed by a qualified electrician or electronics technician. De-energize the circuit completely before replacing the fuse and verify the fuse holder is rated for the 5x20 mm cartridge form factor. Confirm replacement amperage matches the circuit protection requirement exactly, as substituting a higher-rated fuse can defeat overcurrent protection. Applicable installations should comply with NEC guidelines for control circuit overcurrent protection.
