Glass fuse for 125 V circuits

This Bussmann GMC-6-R glass fuse is rated at 6 A and 125 V AC with a 10 kA interrupt rating. The time-delay, cylindrical body suits equipment that experiences brief inrush currents. Each pack contains five fuses for spares or multi-point protection. It fits standard 5 mm × 20 mm fuse blocks such as the HTB series.

Time-delay glass construction

The glass body allows visual confirmation of the element status after a fault. Time-delay operation prevents nuisance opening during temporary overloads while still interrupting short-circuit current up to 10 kA at 125 V AC. The non-rejection design accepts standard clip-type holders without a keyed slot. No active cooling or moving parts are involved, so operation is silent.

Five-piece pack with cross-reference data

The pack supplies five identical fuses, reducing downtime when a replacement is needed. Equivalent series references include Littelfuse 239 and Mersen GSC for easy sourcing alternatives. Certifications cover CE, CSA Class 1422-01 and UL 248-14 Guide JDYX, confirming compliance for North American installations. Buyers who need a higher voltage rating or a different amperage must select another part number.

Questions about this item

How do I install the GMC-6-R fuse and what step is often missed?

Insert the 20 mm x 5 mm cylindrical glass body into a compatible HTB fuse block until the metal caps seat fully; the step often missed is confirming the 10 kA interrupt rating at 125 V AC matches the circuit's prospective fault current.

What maintenance or replacement will the GMC-6-R fuse need later?

As a single-element, time-delay glass fuse it is not serviceable; after any over-current event that opens the element, replace the entire fuse with another 6 A, 125 V AC, 10 kA rated unit from the 5-pack.

What limit appears first when the GMC-6-R fuse runs under sustained load?

The 6 A continuous current rating is the first limit; operating above 6 A will cause the time-delay element to melt, while the 10 kA interrupt rating only applies during short-circuit faults.
