Bussmann ABC-5-R 5A Fast Acting Ceramic Fuse 250VAC 125VDC 5PK
Fast-acting ceramic fuse rated 5 A at 250 V AC and 125 V DC, supplied as a five-pack for circuit protection
- 5 A fast-acting protection for sensitive circuits
- 250 V AC / 125 V DC rating fits mixed-voltage panels
- 10 kA interrupt capacity at 125 V handles heavy fault currents
- Ceramic body withstands high heat without shattering
- 1-1/4 in × 1/4 in cylindrical size matches standard fuse blocks
5 A fast-acting ceramic fuse for circuit protection
The Bussmann ABC-5-R is a 5 A fast-acting cylindrical ceramic fuse rated for 250 V AC and 125 V DC. It is designed for non-rejection fuse blocks and carries a 10 kA interrupt rating at 125 V AC and DC. The single-element construction provides reliable overcurrent protection for compatible equipment.
Sustained-load behaviour and interrupt capacity
Under continuous operation the fuse opens quickly when current exceeds its 5 A rating, limiting energy let-through during fault conditions. The ceramic body withstands high interrupting energy with a 200 A rating at 250 V AC and 10 kA at 125 V DC. It is non-indicating, so visual confirmation requires external inspection or testing.
Replaces ABC, 314 and GAB series fuses in 1-1/4
This pack of five directly substitutes for Bussmann ABC, Littelfuse 314 and Mersen GAB series fuses of the same dimensions and ratings. The upgrade is worth it when existing fuses show ageing, when a certified 10 kA interrupt rating is required, or when standardising spares for fuse blocks such as the 3823, HFA, HHN, HK, HKP, HPF, HRK, HTB and S-8000 series.

Questions about this item
Does the ceramic body of the ABC-5-R fuse run hot or make noise during continuous operation?
The ceramic body and single-element design are passive; the fuse produces no noise and generates no measurable heat under normal load until it interrupts a fault at its rated 10 kA at 125 V AC or 200 A at 250 V AC.
Which fuse blocks are required to mount these 1-1/4 in by 1/4 in cylindrical fuses?
Compatible fuse block series include 3823, HFA, HHN, HK, HKP, HPF, HRK, HTB and S-8000, all of which accept the 1-1/4 in length and 1/4 in diameter of the ABC-5-R.
Can the ABC-5-R replace older glass fuses in equipment rated for 250 V AC and 125 V DC?
Yes, the ceramic ABC-5-R matches the 5 A, 250 V AC and 125 V DC ratings of legacy glass types such as Littelfuse 314 and Mersen GAB, and its 10 kA interrupt rating at 125 V AC and 125 V DC meets or exceeds those older parts.
