Bussmann

Bussmann S-25 Plug Fuse 25A 10kA 125V 4 PK

SKU CH-7BF6-AD7EY

Pack of four 25 A ceramic plug fuses with time-delay, indicating function and 10 kA interrupt rating at 125 V AC

  • Time-delay operation protects motors from nuisance trips
  • 10 kA interrupt rating handles high fault currents safely
  • Dual-element design combines overload and short-circuit protection
  • Rejection-style base prevents installation of incorrect fuse ratings
  • Ceramic body meets UL 248-11 and CSA Class 1423-01 standards

Bussmann S-25 Plug Fuse 25A 125V

This Bussmann S-25 plug fuse provides 25A circuit protection at 125V AC with a 10kA interrupt rating. The ceramic-bodied, time-delay design handles temporary overloads without nuisance opening. A rejection base prevents installation in incorrect Edison sockets. The pack contains four fuses for residential or light-commercial fuse panels.

Suits 25A 125V circuits needing time-delay

These fuses suit 25A branch circuits that require time-delay performance and a visible indication link. They are not for circuits rated above 125V AC or for applications demanding a faster-acting characteristic. Buyers needing a different amperage or voltage rating must select another part. The indicating feature helps locate a blown fuse quickly.

25A 125V AC rating with 10kA interrupt

The single specification that decides fit is the 25A, 125V AC rating combined with a 10kA interrupting capacity. Verify the panel requires a Type S rejection-base fuse before purchasing. The UL 248-11 listing and CSA certification confirm compliance with North American safety standards. Each fuse uses a dual-element construction for reliable overload and short-circuit response.

Questions about this item

Which pack size should I choose for this plug fuse?

The only option listed is a 4 PK containing four identical 25 A fuses.

What does the 10 kA interrupt rating mean when the fuse is installed?

It can safely break a fault current of up to 10 000 amperes at 125 V AC without rupturing.

Which standard governs the 125 V AC rating and how does it limit use?

UL 248-11 certifies the fuse for 125 V AC circuits; do not apply it above that voltage.
