Cooper Bussmann GDC-3.15A Cartridge Time Delay Fuse 3.15A

Product Description

The COOPER BUSSMANN GDC-3.15A is a glass cartridge time delay fuse rated at 3.15 amps, designed for circuit protection in low-current electronic and instrumentation applications. The time delay characteristic allows temporary inrush currents to pass without nuisance tripping, while still interrupting sustained overloads and fault conditions. At 20 mm in overall length and 5 mm in diameter, this is a standard 5x20 mm miniature fuse body compatible with a wide range of panel-mount and PCB-mounted fuse holders. Electricians, controls technicians, and electronics service professionals install this fuse when servicing equipment that requires IEC 60127-2 compliant overcurrent protection.

This fuse is suited for residential and commercial electronic control panels, HVAC control boards, instrumentation enclosures, and light industrial equipment where a 5x20 mm time delay fuse is specified. The glass body allows visual inspection for a blown element without removing the fuse from its holder, which speeds up fault diagnosis during service calls. Applications calling for internationally certified miniature fuse protection in the 3.15 A range are the primary fit. Always verify the fuse holder accepts a 5x20 mm cartridge before installation.

Key Features

• Time delay rating absorbs inrush current spikes without nuisance tripping
• Glass body enables quick visual confirmation of fuse condition
• Standard 5x20 mm form factor fits a broad range of panel and PCB fuse holders
• Carries multiple international certifications including IEC 60127-2, CSA, cURus, CCC, SEMKO, PSE, and IMQ
• Miniature cartridge construction suits space-constrained control enclosures

Compatibility

Designed as an OEM-style replacement for 5x20 mm time delay cartridge fuse positions in electronic control equipment requiring a 3.15 A, IEC 60127-2 rated fuse.

Installation Notes

Power down and de-energize the equipment completely before replacing any fuse. Confirm the replacement fuse matches the original amperage rating and time delay designation — substituting a fast-acting fuse or a higher-amperage fuse in a time delay application can damage equipment or create a safety hazard. Use the appropriate fuse puller for the fuse holder style to avoid cracking the glass body. Installation should comply with applicable electrical codes and the equipment manufacturer's service documentation.
