Cooper Bussmann GMD-1.5-R Cartridge Time Delay Fuse 1.5A

Product Description

The COOPER BUSSMANN GMD-1.5-R is a glass-body cartridge time delay fuse rated at 1.5 amps, designed for overcurrent protection in low-current electronic and electrical circuits. The mini cartridge form factor measures 20 mm in overall length and 5 mm in diameter. Time delay action allows brief inrush currents to pass without nuisance opening, making it well suited for circuits with motor loads, transformers, or capacitive inrush. Interrupting rating is 10,000 amps at 125 volts and 35 amps at 250 volts. Licensed electricians and electronics technicians install this fuse type in panel sub-circuits, instrumentation, and control boards where precision overcurrent protection is required.

The GMD-1.5-R fits 5 mm x 20 mm fuse holders commonly found in residential and light commercial control panels, instrumentation enclosures, and small appliance circuits. Its glass body allows visual inspection of the fuse element without removal, a practical advantage during routine service. This fuse is appropriate wherever a 5 mm x 20 mm time delay cartridge fuse is specified at 1.5 A, and it carries multiple international certifications making it suitable for North American, Japanese, and European equipment.

Key Features

• 1.5 amp time delay rating tolerates brief inrush currents without nuisance blowing
• Glass cartridge body allows visual fuse-element inspection without removal
• Mini 5 mm x 20 mm form factor fits standard IEC-style fuse holders
• 10,000 amp interrupting rating at 125 volts for reliable fault clearing
• Multi-standard certified: UL Listed, CSA Certified, PSE/JET, and RoHS compliant

Compatibility

Designed as an OEM-style replacement for 5 mm x 20 mm time delay cartridge fuse positions in control panels, instrumentation, and light commercial electrical equipment requiring a 1.5 amp slow-blow fuse.

Installation Notes

Installation and replacement of fuses must be performed by a qualified electrician or trained technician following applicable NEC requirements. Always de-energize and verify the circuit is dead before removing or installing a fuse. Never substitute a fuse with a higher amperage rating. Confirm the fuse holder accepts the 5 mm x 20 mm cartridge form factor and is rated for the circuit voltage before installation.
