  • 25 A time-delay plug fuse protects motor circuits from overloads
  • 10 kA interrupt rating at 125 V AC clears high fault currents safely
  • Dual-element construction handles temporary surges without nuisance opening
  • Ceramic body with indicating window shows blown status at a glance
  • UL 248-11 listed and CSA certified for code-compliant installations

What this fuse is and who needs it

The Bussmann S-6-1/4 plug fuse provides 6.25 A time-delay protection at 125 V AC with a 10 kA interrupt rating. The ceramic body contains a dual-element design that resists nuisance opening during motor start-up. The pack contains four fuses for residential or light-commercial panels.

What it replaces and when to upgrade

This S-series fuse replaces Edison-base S, SLO or SOO types from Littelfuse or Mersen. The rejection base prevents installation in a socket rated for a higher current. Upgrade when an existing fuse has blown or when a circuit requires the time-delay characteristic for inductive loads.

Check your panel before ordering

Verify the panel uses Edison-base rejection sockets rated for 125 V AC. Confirm the circuit ampacity matches the 6.25 A rating and that the interrupt capacity meets the 10 kA requirement. The fuses carry UL 248-11, CSA Class 1423-01 and CE markings.

Questions about this item

What size fuse base does the 6.25 A plug fuse screw into?

The S-series plug fuse fits a standard Edison-base socket rated for 125 V AC.

Which step is most often missed when installing the time-delay plug fuse?

Align the rejection tab on the ceramic body with the slot in the fuse holder so the fuse seats fully.

How do I know when one of the four fuses has blown and needs replacement?

The indicating window changes colour, giving a visual signal that the dual-element fuse has opened.
