Mersen GGC20 Fast-acting Glass Fuse 20A 32V

Product Description

The MERSEN GGC20 is a fast-acting miniature glass fuse rated at 20 amps and 32 volts AC, built in the standard 0.25 inch x 1.25 inch (6.3x32mm) ferrule form factor. Fast-acting fuses open the circuit immediately upon an overcurrent condition, providing direct protection for sensitive equipment with no intentional time delay. This GGC-series fuse is sized for compact electrical enclosures and control panels where space is limited. Electricians and control panel builders rely on this fuse type to protect low-voltage circuits in a wide range of light commercial and industrial applications.

This fuse is suited for use in miniature fuse holders and fusible terminal blocks that accept the 0.25 inch x 1.25 inch ferrule form factor. Typical applications include control circuit protection, instrumentation panels, HVAC control boards, and small appliance service. The fast-acting response characteristic makes it appropriate for resistive loads and circuits where downstream components cannot tolerate sustained overcurrent.

Key Features

• Fast-acting response for immediate overcurrent interruption with no time delay
• 20-amp current rating for control and instrumentation circuit protection
• 32-volt AC rating suited for low-voltage control circuits
• Standard 0.25 inch x 1.25 inch glass ferrule body fits widely available fuse holders
• Glass tube body allows visual inspection of fuse element without removal

Compatibility

Designed as an OEM-style replacement for miniature fast-acting ferrule fuses in the standard 0.25 inch x 1.25 inch (6.3x32mm) form factor, compatible with fuse holders and fusible terminals rated for this size.

Installation Notes

Fuse replacement should be performed by a qualified electrician or control technician. Always de-energize and lock out the circuit before removing or installing a fuse. Verify the replacement fuse matches the original amperage and voltage rating exactly before reinstalling. Never substitute a higher-rated fuse to bypass a nuisance-trip condition without first diagnosing the root cause of the overcurrent.
