What it is
The Bussmann GMA-8-R is a glass tube fuse rated at 8 A and 125 V AC with a 200 kA interrupt rating. It comes in a pack of five and suits low-voltage circuits that require fast-acting overcurrent protection in a compact 20 mm by 5 mm cylindrical body.
The specification that matters
The interrupt rating of 200 kA at 125 V AC determines whether this fuse can safely clear a fault on your circuit. If your application demands a higher breaking capacity or a different voltage rating, this part will not meet the requirement.
Installation and common issues
The cylindrical 20 mm by 5 mm body fits standard HTB-series fuse blocks and equivalent holders from Littelfuse 235 or Mersen GGM series. A loose clip or oxidised contact often causes nuisance heating, so verify the holder grip and clean the terminals before fitting.

Questions about this item
What does the 8 A rating mean for a circuit using this fuse?
The fuse will carry up to 8 A continuously and open quickly if current exceeds that value, protecting wiring and components downstream.
How does the 200 kA interrupt rating at 125 V AC limit real-world use?
It means the fuse can safely break fault currents up to 200 kA at 125 V AC; circuits with higher prospective short-circuit current need a higher-rated device.
What holder or block fits the 20 mm by 5 mm cylindrical glass body?
It fits standard 5 mm × 20 mm fuse clips or blocks such as the HTB series, which accept this non-rejection cylindrical form factor.
