Bussmann ABC-1/4-R Ceramic Fuse 0.25A 10kA 125V AC/DC line protection

SKU CH-EPN7-BWRQQ

Ceramic fast-acting fuse rated 0.25 A with 10 kA interrupt capacity at 125 V AC and DC

  • Fast-acting protection clears faults quickly
  • 10 kA interrupt rating handles high fault currents
  • Ceramic body withstands thermal stress
  • 25 A rating suits low-current circuits
  • Compatible with standard fuse blocks for easy installation

Circuit Protection Fuse

The Bussmann ABC-1/4-R is a ceramic fuse rated at 0.25 amps for line protection in AC and DC circuits. It suits maintenance technicians and panel builders who need a fast-acting, non-indicating fuse with a 10kA interrupt rating at 125 volts.

Sustained Load Behaviour

The fuse carries its rated current continuously and opens quickly when that value is exceeded. Its ceramic body withstands the thermal stress of repeated fault interruption without degradation, maintaining the stated 10kA breaking capacity at 125 volts AC or DC over the device's service life.

Interrupt Rating Decides Fit

The single specification that determines suitability is the 10kA interrupt rating at 125 volts. If the prospective fault current at the installation point exceeds this value, the fuse cannot safely clear the fault and a higher-rated device must be selected instead.

Questions about this item

How much heat or power does the ABC-1/4-R fuse dissipate during continuous 0.25 A operation?

The fuse is rated for 0.25 A at 125 V AC or DC with a 10 kA interrupt rating; power loss depends on the circuit voltage drop across the element.

What fuse block or holder series must I already have to mount this 1-1/4 in x 1/4 in ceramic body?

Compatible fuse block series include 3823, HFA, HHN, HK, HKP, HPF, HRK, HTB and S-8000.

Will this fast-acting ABC fuse coordinate with older 314 or GAB series fuses already installed in the same panel?

It is listed as equivalent to Bussmann ABC, Littelfuse 314 and Mersen GAB series, so it can replace those types directly.
