Mersen GGC25 Fast-acting Miniature Glass Fuse 25A

Product Description

The MERSEN GGC25 is a fast-acting miniature glass fuse rated for 25 amps and up to 250 volts AC. It uses a ferrule (cylindrical) form factor measuring 0.25 inches by 1.25 inches, also known as the 6.3x32mm size class common in European and international panel applications. Fast-acting fuses respond immediately to overcurrent conditions without intentional time delay, making them suitable for circuits that require direct, no-delay protection of sensitive components. Licensed electricians and panel technicians install this fuse during new construction, equipment service, and control panel maintenance.

This fuse is used in low-voltage control circuits, instrumentation panels, industrial equipment, and light commercial electrical enclosures. Its compact size and ferrule termination style make it compatible with standard fuseholder clips and inline fuse blocks designed for the 0.25-inch by 1.25-inch form factor. Applications include power supplies, signal equipment, and branch circuit protection in panels where fast-acting response is specified by the equipment manufacturer.

Key Features

• Fast-acting response with no intentional time delay for direct overcurrent protection
• Glass body allows visual inspection of fuse element without removal
• 25A current rating for moderate-load circuit protection
• Rated up to 250 volts AC
• Standard 0.25-inch by 1.25-inch ferrule form factor fits widely available fuseholders

Compatibility

Designed as an OEM-style replacement for fast-acting miniature ferrule fuses in the 0.25-inch by 1.25-inch (6.3x32mm) size class used in control panels, industrial equipment, and instrumentation enclosures.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. Always de-energize and lock out the circuit before replacing a fuse. Verify the replacement fuse matches the original amperage and voltage rating before installation. Do not install a fuse with a higher amperage rating than what the circuit or equipment manufacturer specifies.
