Glass Fuse for 250 V AC Circuits
This pack contains five Bussmann GMD-series glass fuses rated at 315 mA for 250 V AC circuits. They suit equipment that requires a time-delay cylindrical fuse with a 20 mm by 5 mm body. The non-rejection design fits compatible HTB-series fuse blocks. Each fuse carries CE, CSA and UL 248-14 markings.
10 kA Interrupt Rating at 125 V AC
The single specification that decides fit is the interrupt rating of 10 kA at 125 V AC, with a 100 A rating at 250 V AC. This defines the maximum fault current the fuse can safely break. Buyers whose equipment demands a higher interrupt capacity at either voltage cannot use these fuses.
Handles 315 mA Continuous Load
The 315 mA rating provides headroom for small transient surges in low-power control circuits, lighting ballasts or instrument power supplies. The time-delay characteristic prevents nuisance opening during brief inrush. The fuse will open once sustained current exceeds the rating or when fault current surpasses the stated interrupt limits.

Questions about this item
What does the 315 mA rating mean for a circuit using this fuse?
The fuse will carry up to 315 mA continuously and open after a time delay if the current exceeds that value.
How do the 100 A at 250 V AC and 10 kA at 125 V AC interrupt ratings limit fault protection?
The fuse can safely break a short-circuit current of 100 A at 250 V AC or 10 kA at 125 V AC; above those levels it may not clear the fault.
What holder or block is needed to mount the 20 mm by 5 mm cylindrical glass body?
A fuse block that accepts 20 mm long, 5 mm diameter cylindrical fuses such as the HTB series will fit this fuse.
