Small cylindrical ceramic fuse with metal end caps

Eaton Bussmann

Eaton Bussmann MDA-12-R Ceramic Fuse 12A 10kA 125V 750A 250V line protection

SKU CH-XZD6-8KKJ1

A 12 A time-delay ceramic fuse rated for 10 kA at 125 V AC and 750 A at 250 V AC

  • 12 A time-delay ceramic fuse protects against sustained overloads
  • 10 kA interrupt rating at 125 V AC handles high fault currents safely
  • 750 A interrupt rating at 250 V AC provides reliable line protection
  • Ceramic body construction resists heat and mechanical stress during operation
  • Compatible with 3823, HFA, HHN, HK, HKP, HPF, HRK, HTB, S-8000 fuse blocks for versatile installation

Circuit Protection for 12 A Circuits

This ceramic fuse interrupts 10 kA at 125 V AC and 750 A at 250 V AC. It suits technicians and maintenance teams who need reliable line protection for control panels, lighting ballasts or small motor circuits.

Cylindrical Ceramic Body with Non-Rejection Fit

The 1-1/4 in by 1/4 in ceramic tube fits standard fuse blocks including series 3823, HFA, HHN, HK, HKP, HPF, HRK, HTB and S-8000. Non-rejection mounting means it drops into existing clips without keying changes, while the ceramic body withstands high interrupt energy.

Time-Delay Characteristic for Inrush Tolerance

The MDA-series time-delay element rides through transformer magnetising current or motor starting surges without nuisance opening. It is not for buyers who need fast-acting semiconductor protection or an indicating flag for instant fault location.

Questions about this item

What interrupt rating does the 12 A ceramic fuse provide at 125 V AC?

The fuse interrupts up to 10 kA at 125 V AC and 750 A at 250 V AC.

What physical dimensions and fuse block series does this MDA-12-R fit?

It measures 1-1/4 in long by 1/4 in diameter and fits blocks such as 3823, HFA, HHN, HK, HKP, HPF, HRK, HTB and S-8000.

How is the time-delay fuse installed and what common error should be avoided?

Insert the cylindrical fuse into a compatible holder until fully seated; do not force a rejection-type fuse into a non-rejection block.
