Mersen GGX1 Fast-acting Glass Fuse 1A 250V

Product Description

The MERSEN GGX1 is a fast-acting glass fuse rated at 1 amp and 250 volts AC, built to the 8AG form factor measuring 0.25 inches in diameter and 1 inch in length. It is designed for overcurrent protection in control circuits, instrumentation panels, and low-voltage electrical equipment where a rapid response to fault conditions is required. The ferrule-style connection terminals seat securely in clip-mount fuse holders, making replacement straightforward for electricians and electronics technicians working on panel boards or control assemblies.

This fuse is commonly used in residential and light commercial electrical panels, HVAC control boards, and instrumentation equipment that calls for a standard 8AG glass fuse. The 5x20mm glass body construction provides a clear visual indicator of a blown element, allowing technicians to confirm fuse condition without additional test equipment. Its fast-acting speed characteristic makes it appropriate for circuits without high inrush loads that could cause nuisance opens.

Key Features

• Fast-acting speed characteristic for quick overcurrent response
• 250V AC rated voltage suitable for standard control circuit applications
• 1A current rating for low-draw instrumentation and control circuits
• Ferrule connection terminals compatible with clip-style fuse holders
• Glass body allows visual inspection of the fuse element without tools
• Compact 0.25 x 1 inch form factor fits standard 8AG fuse holders

Compatibility

Designed as an OEM-style replacement for standard 8AG fast-acting glass fuses rated at 1A and 250V in clip-mount fuse holders used across HVAC controls, instrumentation, and general electrical equipment.

Installation Notes

Installation should be performed by a qualified electrician or technician. Always de-energize and lock out the circuit before removing or installing a fuse. Confirm the replacement fuse matches the amperage and voltage rating of the original before seating it in the holder. Follow applicable NEC guidelines for overcurrent protection when selecting or replacing fuses in panel or control applications.
