Ceramic fuse for 250 V AC circuits
The Bussmann ABC-4-R is a fast-acting cylindrical ceramic fuse rated at 4 A for 250 V AC and 125 V DC. It comes in a pack of five and suits maintenance or replacement tasks on equipment that uses this fuse size and rating.
Interrupt ratings define safe fault current
The fuse interrupts up to 10 kA at 125 V AC and 125 V DC, and up to 200 A at 250 V AC. Circuits with higher prospective short-circuit current need a fuse with a greater interrupt rating, so this part cannot be used where the available fault current exceeds those values.
4 A rating selects the protected load
The 4 ampere rating is the single specification that decides whether this fuse matches the circuit design. A lower rating will nuisance-blow under normal load; a higher rating will not open quickly enough to protect wiring and components sized for 4 A.

Questions about this item
Which Bussmann ABC-series fuse should I pick for a 4-amp, 250 V AC circuit?
Choose the ABC-4-R; it is rated 4 A at 250 V AC and 125 V DC, fast-acting, and comes in a 5-pack.
What does the 10 kA interrupt rating at 125 V mean when the fuse is installed?
It means the fuse can safely break a fault current up to 10 kA at 125 V AC or DC without rupturing.
What fuse block series accept this 1-1/4 × 1/4 inch ceramic body?
Compatible blocks include series 3823, HFA, HHN, HK, HKP, HPF, HRK, HTB and S-8000.
