Five glass cylindrical fuses 20mm long 5mm diameter 125mA 250V AC 35A interrupt rating

Bussmann

Bussmann S506-125-R Glass Fuse 125mA 250V 35A 5 PK

SKU CH-82PY-2E1TN

Pack of five glass time-delay fuses rated 125 mA at 250 V AC with a 35 A interrupt rating

  • Time-delay protection prevents nuisance blows
  • 125 mA rating suits low-current circuits
  • 250 V AC rating covers mains voltage
  • 35 A interrupt rating handles fault currents
  • Pack of five provides ready spares

Glass Fuse 125 mA 250 V AC

These Bussmann S506 series glass fuses protect low-current circuits rated for 125 mA at 250 V AC. Each cylindrical fuse measures 20 mm long by 5 mm in diameter and carries a time-delay characteristic. The pack contains five pieces for service or replacement stock.

Suits maintenance on equipment using GDC 218

Technicians servicing devices specified for Bussmann GDC, Littelfuse 218 or Mersen GDG equivalents will find a direct match. Buyers needing a different current rating, voltage rating or a rejection-type body should select another part.

Time-delay action with 35 A interrupt rating

The fuse opens on sustained overload while tolerating brief inrush, and it safely interrupts up to 35 A at 250 V AC. This single specification determines whether the device meets the circuit's protection requirements.

Questions about this item

Will the 20 mm by 5 mm glass body fit the fuse holder I already use for Bussmann GDC or Littelfuse 218 types?

Yes, the S506-125-R shares the 20 mm length and 5 mm diameter of the GDC and 218 series, so it drops into the same HTB-compatible fuse blocks without modification.

How can I confirm the time-delay characteristic is operating correctly once the fuse is installed?

A time-delay fuse tolerates brief inrush currents above 125 mA without opening; if the circuit starts reliably and the fuse remains intact during normal start-up surges, the delay function is working as intended.

Does the pack of five include any fuse blocks or holders, or must I supply those separately?

The package contains only the five glass fuses; compatible HTB-series fuse blocks or equivalent holders are sold separately.
