Four ceramic plug fuses with glass indicating windows in a blister pack

Bussmann

Bussmann S-14 Plug Fuse 14A 10kA 125V AC 4 PK

SKU CH-TB6C-XB61N

Four 14 A time-delay plug fuses with 10 kA interrupt rating at 125 V AC

  • 14 A time-delay protects circuits from temporary overloads
  • 10 kA interrupt rating at 125 V AC handles high fault currents
  • Dual-element ceramic body gives reliable indicating performance
  • UL 248-11 and CSA Class 1423-01 listed for code compliance
  • Pack of 4 fuses provides ready spares for maintenance

Bussmann S-14 Plug Fuse 14A 4 Pack

The Bussmann S-14 is a ceramic-bodied plug fuse rated at 14 amperes and 125 volts AC. It suits residential or light-commercial fuse panels that accept Edison-base rejection-type fuses. The time-delay characteristic tolerates brief motor-start surges without nuisance opening. The pack contains four fuses for multi-circuit protection or spares.

10 kA Interrupt Rating at 125 V AC

The interrupting capacity of 10 kiloamperes at 125 volts AC is the critical specification for safe application. It must equal or exceed the available short-circuit current at the point of installation. UL 248-11 listing and CSA Class 1423-01 certification confirm compliance with North American safety standards for branch-circuit overcurrent protection.

Dual-Element Time-Delay for Motor Loads

The dual-element construction provides overload tolerance for inductive loads such as small compressors or pump motors up to the 14 ampere rating. It opens quickly on dead shorts while riding through normal inrush currents. The fuse is not suited for circuits requiring faster-acting or higher-voltage links, nor for panels that accept only Type-S adapters without the rejection feature.

Questions about this item

How much current does the 14 A fuse actually allow before it opens in a real circuit?

The fuse is rated at 14 A and provides time-delay operation, so it tolerates brief overloads but will interrupt sustained current above 14 A within its dual-element characteristic curve.

What does the 10 kA at 125 V AC interrupt rating cap in practice?

It means the fuse can safely break fault currents up to 10 kA on a 125 V AC supply without rupturing, meeting UL 248-11 and CSA Class 1423-01 requirements.

What physical space and socket style does the S-series plug body need to fit?

The ceramic S-series body uses a standard Edison-base plug fuse socket and the rejection feature prevents insertion into non-rejection bases.
