Bussmann

Bussmann MDA-1-R Ceramic Fuse 1A 10kA 125V 35A 250V 5pk

SKU CH-2ZDZ-GQ6JF

Ceramic time-delay fuse rated 1 A with 10 kA interrupting at 125 V AC and 35 A at 250 V AC, supplied in a pack of five

  • Time-delay operation prevents nuisance trips
  • 10 kA interrupt rating at 125 V AC handles high fault currents
  • 35 A interrupt rating at 250 V AC protects 250 V circuits
  • Ceramic body withstands thermal and mechanical stress
  • Standard 1-1/4 × 1/4 in size fits common fuse blocks

Fuse type and rating

The Bussmann MDA-1-R is a ceramic time-delay fuse rated at one ampere with interrupt ratings of ten kiloamperes at 125 volts AC and thirty-five amperes at 250 volts AC. It comes in a pack of five for maintenance or replacement stock.

Voltage and interrupt limits

This fuse operates at up to 250 volts AC and is designed to clear faults safely within its published interrupt ratings. It is not suitable for circuits exceeding these voltage or fault-current levels.

Physical size and series compatibility

The cylindrical body measures one and a quarter inches long by one quarter inch in diameter and fits fuse block series such as 3823, HFA, HHN, HK, HKP, HPF, HRK, HTB and S-8000. Builders needing a different body style or rejection-type fuse cannot use this part.

Questions about this item

Should I pick the 1 A ceramic fuse or a different amperage for my circuit?

Choose the 1 A rating only if your circuit is designed for 1 A; the pack contains five identical 1 A fuses, so there is no alternative amperage in this listing.

What does the 10 kA at 125 V AC interrupt rating mean when the fuse is installed?

It means the fuse can safely break a fault current of up to 10 kA on a 125 V AC supply without rupturing.

Which fuse blocks accept this 1/4 in x 1-1/4 in ceramic body?

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