Mersen GDL30 Glass Fuse 30A 32V 5-pack

Product Description

The MERSEN GDL30 is a 30-amp, 32-volt glass fuse designed to protect low-voltage electrical circuits from overcurrent conditions. Sold in a 5-pack, this fuse is a standard format used in automotive, HVAC control wiring, and light industrial applications where compact overcurrent protection is required. The glass body allows for quick visual inspection of the fuse element without removing it from the holder, reducing diagnostic time during service calls. Licensed electricians and HVAC technicians commonly stock this fuse type for field repairs and panel maintenance.

The GDL30 is suited for low-voltage DC circuits rated at 32 volts and 30 amps. Typical applications include control circuit protection in HVAC equipment, automotive wiring harnesses, marine electrical systems, and light-duty industrial control panels. The compact dimensions make it compatible with standard inline and panel-mount glass fuse holders found across a wide range of equipment. The 5-per-pack quantity is practical for service technicians carrying spares on the job.

Key Features

• 30-amp current rating for reliable overcurrent protection in demanding circuits

• Glass body allows immediate visual inspection of fuse element without removal
• Compact form factor fits standard glass fuse holders
• Sold in a 5-pack for convenient field stocking

Compatibility

Designed as an OEM-style replacement glass fuse for low-voltage DC control circuits and equipment requiring a 30-amp, 32-volt glass fuse in a standard inline or panel-mount holder.

Installation Notes

Glass fuses of this type are installed by qualified electricians or HVAC technicians following applicable NEC guidelines for overcurrent protection. Always de-energize and verify the circuit is unpowered before replacing a fuse. Confirm the replacement fuse matches the exact amperage and voltage rating of the original — never substitute a higher-rated fuse to address repeated blowing without first diagnosing the root cause. Use an appropriately rated fuse puller or insulated tool when removing fuses from live panels where full de-energization is not possible.
