Cooper Bussmann GDA-500MA Cartridge Fast-acting Fuse 0.5A

Product Description

The COOPER BUSSMANN GDA-500MA is a ceramic cartridge fast-acting fuse rated at 0.5 amps, designed for overcurrent protection in low-current electronic and control circuits. Built to the IEC 60127-2 standard for miniature fuses, this 20 mm fuse fits standard 5 mm diameter fuse holders found in industrial controls, instrumentation panels, and commercial HVAC equipment. The ceramic body provides reliable arc suppression and withstands higher fault currents compared to glass-body alternatives, making it suitable for demanding service environments. Licensed electricians, controls technicians, and electronics service professionals specify this fuse for precision overcurrent protection in sensitive low-voltage circuits.

The GDA-500MA is suited for residential and commercial applications where a 20 mm x 5 mm mini cartridge fuse position is required. Common install scenarios include control boards, instrumentation devices, electronic equipment power supplies, and low-voltage protection circuits. The fast-acting timing response makes it appropriate for circuits without high inrush loads, where immediate interruption on overcurrent is required. This fuse is sold individually but requires a minimum order quantity of 5 units.

Key Features

• Fast-acting fuse timing for immediate overcurrent interruption in sensitive circuits
• Ceramic body construction provides superior arc suppression compared to glass alternatives
• 20 mm overall length and 5 mm diameter fits standard IEC mini fuse holders
• Meets IEC 60127-2, UL Recognized (JDYX2 File E19180), CSA, CCC, SEMKO, and IMQ certifications
• RoHS compliant construction
• Mini fuse form factor suitable for space-constrained panel and board installations

Compatibility

Designed as a direct-fit replacement for standard 20 mm x 5 mm IEC mini cartridge fuse positions in electronic control boards, instrumentation equipment, and commercial HVAC or electrical control panels requiring a 0.5 A fast-acting fuse.

Installation Notes

Installation should be performed by a qualified electrician or controls technician. Always de-energize and lockout the equipment before replacing fuses, following NFPA 70E safe work practices. Verify the replacement fuse amperage and time-delay rating match the circuit requirements exactly before installing. Never substitute a higher-rated fuse to restore power to a faulted circuit without first identifying and correcting the underlying fault.
