Bussmann S506-630-R Glass Fuse 630mA 250V 35A 5PK
A pack of five 20 mm glass time-delay fuses rated at 630 mA and 250 V AC with a 35 A interrupt rating
- Time-delay protection handles surges without nuisance blows
- 35 A interrupt rating at 250 V AC clears faults safely
- 630 mA rating matches precise circuit requirements
- Glass cylindrical body 20 mm × 5 mm fits standard holders
- Pack of five provides ready spares for maintenance
Glass fuse for low-current protection
The Bussmann S506-630-R is a 20 mm by 5 mm cylindrical glass fuse rated at 630 mA and 250 V AC with a time-delay characteristic. It suits equipment that needs a small non-rejection fuse for single-element overcurrent protection.
Pack of five with cross-reference series
Each pack contains five fuses and the series is equivalent to Bussmann GDC, Littelfuse 218 and Mersen GDG types. The interrupt rating is 35 A at 250 V AC and the fuses carry cURus recognition, IMQ approval and MITI/JET certification 1641-31003-1005.
Simple snap-in installation with block compatibility
The cylindrical body fits compatible HTB fuse blocks and similar holders without tools. Ensure the holder accepts a 5 mm diameter by 20 mm length glass fuse and that the circuit voltage does not exceed 250 V AC. Using a higher-rated fuse or a fast-acting type where time-delay is required can prevent proper fault clearing.

Questions about this item
Does the S506-630-R fuse need periodic replacement or maintenance?
The fuse is a single-element, non-rejection glass device rated 630 mA at 250 V AC with a 35 A interrupt rating; it operates until it blows and then must be replaced, with no scheduled maintenance required.
What limits continuous operation of the 630 mA time-delay fuse first?
The 630 mA current rating is the limit; sustained current above this value will cause the fuse to open, while the 35 A interrupt rating only applies during a fault.
How much heat or power does a pack of five 20 mm × 5 mm glass fuses generate when running all day?
Each fuse carries up to 630 mA at 250 V AC; normal dissipation is low and the glass body stays cool under rated load, with no forced cooling needed.
