Five cylindrical ceramic fuses with metal end caps

Eaton Bussmann

Eaton Bussmann MDA-2-R Ceramic Fuse 2A 250V AC Time-Delay 5 Pack

SKU CH-VNNG-W6YCJ

A pack of five 2 A ceramic time-delay fuses rated for 250 V AC with a 100 A interrupt rating at 250 V and 10 kA at 125 V

  • Time-delay action prevents nuisance trips from motor start-up surges
  • 100 A interrupt rating at 250 V AC protects circuits during short-circuit events
  • 10 kA interrupt rating at 125 V AC handles high fault currents safely
  • Ceramic body construction withstands heat and resists shattering under overload
  • Five-fuse pack provides ready spares for maintenance and replacement needs

Eaton Bussmann MDA-2-R Ceramic Fuse

This pack contains five time-delay ceramic fuses rated at 2A and 250V AC. They are designed for circuit protection in electrical equipment and generator supplies. The cylindrical body measures 1-1/4 in length by 1/4 in diameter. Suitable for maintenance or replacement in compatible fuse blocks.

Time-delay 2A rating with 100A interrupt at 250V AC

The single specification that decides fit is the 2A time-delay characteristic combined with a 100A interrupt rating at 250V AC. This allows the fuse to tolerate brief inrush currents while clearing sustained overloads. A 10kA interrupt rating at 125V AC is also provided. Selecting a different amperage or speed will not protect the circuit correctly.

Fits Bussmann MDA, Littelfuse 326

The fuse fits compatible blocks including series 3823, HFA, HHN, HK, HKP, HPF, HRK, HTB and S-8000. Its non-rejection cylindrical ceramic body slides into standard 1/4 in diameter clips. It is not for buyers who need an indicating fuse or a rejection-type safety fuse. The single-element construction suits general-purpose time-delay applications.

Questions about this item

What does the 100 A interrupt rating at 250 V AC mean for my circuit?

It means the fuse can safely break a fault current up to 100 A at 250 V AC without rupturing, protecting downstream components from severe overloads.

How does the time-delay characteristic affect the 2 A rating in use?

The time-delay element tolerates brief inrush currents above 2 A — such as motor start-up — without nuisance blowing, while still opening on sustained overloads.

Will the 1-1/4 in by 1/4 in ceramic body fit my existing fuse block?

Yes, the cylindrical 1-1/4 in length and 1/4 in diameter match standard 3823, HFA, HHN, HK, HKP, HPF, HRK, HTB and S-8000 series blocks.
