Four small cylindrical ceramic plug fuses in a pack

Bussmann

Bussmann T-8 Plug Fuse 8A 125V 10kA 4 PK

SKU CH-KW1R-W8H4J

Four time-delay plug fuses rated 8 A at 125 V AC with a 10 kA interrupt rating

  • Time-delay protection prevents nuisance tripping
  • Ceramic body withstands 10kA interrupt rating at 125V AC
  • Dual-element design handles temporary overloads safely
  • UL 248-11 and CSA certified for code compliance
  • Four-fuse pack covers multiple circuit positions

Purpose and fit

The Bussmann T-8 plug fuse protects 125 V AC circuits with an 8 A time-delay element. It suits household and light-commercial panels that accept Edison-base fuses and need a 10 kA interrupt rating.

What the pack changes

A four-pack keeps spare fuses on hand so a blown circuit can be restored without a separate trip to the shop. The ceramic body and dual-element design let the fuse ride through brief motor-start surges while still clearing sustained overloads.

Installation and common issues

Screw the fuse into the existing socket until it seats firmly; no tools are required. The most frequent problem is installing a higher-amp fuse in a circuit wired for less current, which defeats the protection.

Questions about this item

How often will the ceramic body need replacement under normal operation?

The ceramic body is a single-use component; once the 8 A dual-element fuse interrupts a fault at 10 kA, the entire plug fuse must be replaced.

What stops the fuse from carrying current continuously at its 8 A rating?

The time-delay, dual-element design tolerates brief overloads but will open if the 8 A rating is exceeded long enough to melt the element.

How much heat does the fuse generate when it runs at 8 A all day?

Normal operation at 8 A produces only the heat typical for a 125 V AC ceramic plug fuse; no additional cooling is required.
