Bussmann ABC-1/2-R ceramic fuse .50A 125V 10kA line protection

SKU CH-Z4GW-HXWGV

Ceramic fast-acting fuse rated 0.5 A at 125 V with 10 kA interrupt capacity

  • Fast-acting response protects sensitive circuits quickly
  • Ceramic body withstands high temperatures during faults
  • 10 kA interrupt rating at 125 V AC handles large fault currents
  • 10 kA interrupt rating at 125 V DC suits DC applications
  • Compatible with multiple fuse block series for easy installation

Ceramic fuse for line protection

The Bussmann ABC-1/2-R is a fast-acting ceramic fuse rated at .5 A with a 10 kA interrupt rating at 125 V AC and 125 V DC. It suits equipment that requires non-rejection, non-indicating overcurrent protection in a cylindrical body. This component is not for circuits needing visual trip indication or rejection-style fuse holders.

Integration into a circuit

The fuse body measures 1-1/4 in length by 1/4 in diameter and fits compatible blocks such as the 3823, HFA, HHN, HK, HKP, HPF, HRK, HTB and S-8000 series. It crosses to Littelfuse 314 and Mersen GAB equivalents, freeing the designer from a single brand choice. It is not for applications that demand a different physical size or a rejection-type footprint.

Thermal and power behaviour

The ceramic body withstands the heat of a 35 A interrupt at 250 V AC while maintaining the 10 kA rating at 125 V. Fast-acting operation clears faults quickly, limiting let-through energy and keeping downstream components cooler. No active cooling or ventilation is required for normal operation.

Questions about this item

How long will the 0.5 A ceramic element hold before it opens under a continuous overload?

The fast-acting design opens quickly once current exceeds 0.5 A; sustained loads above that rating will cause the fuse to blow in seconds rather than minutes.

Does the ceramic body run hot or make noise when it carries 0.5 A all day?

The fuse operates silently and stays cool at its rated 0.5 A; only during a fault does the ceramic body absorb the 10 kA interrupt energy.

Which fuse block series must I already have to mount this 1-1/4 in × 1/4 in cartridge?

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