Bussmann GMC-315-R Glass Fuse 315mA 250V AC
The Bussmann GMC-315-R is a 20mm by 5mm cylindrical glass fuse rated for 315mA at 250V AC. It uses a time-delay design to tolerate brief inrush currents without opening. The pack contains five fuses for spares or multi-point protection in low-power equipment.
Interrupt rating limits fault current handling
The fuse carries a 10kA interrupt rating at 125V AC and 35A at 250V AC. Circuits capable of higher prospective short-circuit current at 250V AC need a fuse with a greater breaking capacity. The non-rejection body style fits standard holders but does not prevent insertion of a lower-rated fuse.
Replaces GMC 239 GSC equivalents in existing holders
This GMC series fuse cross-references Littelfuse 239 and Mersen GSC types, so it fits the same HTB fuse blocks. The jump is worth it when a certified UL 248-14 and CSA Class 1422-01 part is required for compliance. Buyers who need a higher current rating or a different voltage must select another fuse.

Questions about this item
Which pack size should I choose for spares?
The listing supplies a pack of 5 fuses, giving you several replacements in one order.
What does the 315 mA rating mean once the fuse is installed?
It will carry up to 315 mA continuously and open the circuit if the current exceeds that value for a sustained period.
What does the 10 kA at 125 V AC interrupt rating cap in practice?
It means the fuse can safely break a fault current of up to 10 kA on a 125 V AC circuit without rupturing.
