Five cylindrical glass fuses with metal end caps

Bussmann

Bussmann S506-2-R Glass Fuse 2A 250V AC 35A 5 PK

SKU CH-X98X-P7Z0R

Pack of five 2 A, 250 V AC glass time-delay fuses with a 35 A interrupt rating and 20 mm cylindrical bodies

  • 2 A current rating protects low-power circuits
  • Time-delay characteristic tolerates brief inrush surges
  • 35 A interrupt rating at 250 V AC breaks fault current safely
  • Glass body with 20 mm × 5 mm dimensions fits standard fuse blocks
  • Pack of five provides ready spares for maintenance

Purpose & Fit

The Bussmann S506-2-R is a glass time-delay fuse rated at 2 A and 250 V AC for low-current circuit protection. It suits maintenance technicians and panel builders who need a 5 mm by 20 mm cylindrical fuse for compatible holders.

Thermals, Noise & Power Draw

These passive components generate no audible noise and draw no power of their own during normal operation. The glass body provides visible indication of element status while the time-delay characteristic tolerates brief inrush currents without nuisance opening.

Sustained Load Behaviour

Under continuous overload the single-element link melts to interrupt the circuit at an interrupt rating of 35 A at 250 V AC. The fuse is non-rejection style and carries cURus, IMQ and MITI/JET recognition for compliance in approved equipment designs.

Questions about this item

How do I install the 20 mm × 5 mm cylindrical glass fuse into an HTB fuse block, and what is the common mistake?

Insert the fuse straight into the HTB block clips until both metal end caps seat fully; the common mistake is angling the fuse so one cap rests on the clip edge instead of the flat contact surface.

What maintenance or replacement will the S506-2-R fuse need after it operates?

The fuse is a single-element, non-rejection device; once it interrupts a fault at 35 A it must be replaced with another 2 A, 250 V AC time-delay fuse from the 5-pack.

What limit appears first during sustained overload on this 2 A fuse rated for 35 A interrupt at 250 V AC?

The 2 A continuous current rating is reached before the 35 A interrupt rating, so the fuse element melts and opens the circuit at the lower threshold.
