Bussmann GDA-100MA 100mA 250VAC Fast Acting Ceramic Fuse
100 mA 250 V AC fast-acting ceramic fuse with 1.5 kA interrupt rating and 20 mm cylindrical body
- Fast-acting protection interrupts faults quickly
- 100 mA rating suits low-current circuits
- 250 V AC rating handles mains voltage
- Ceramic body withstands high temperatures
- 5 kA interrupt rating clears short circuits safely
Circuit protection for low-current circuits
The Bussmann GDA-100MA is a fast-acting ceramic fuse rated at 100 mA and 250 V AC. It is designed for equipment that requires quick interruption of fault currents in low-power applications. The cylindrical body measures 20 mm long by 5 mm in diameter and fits standard 5 x 20 mm fuse holders.
Replaces 5 x 20 mm fast-acting glass fuses
This ceramic-bodied fuse upgrades from glass equivalents such as the Littelfuse 216 or Bussmann S501 series when higher breaking capacity is needed. The 1.5 kA interrupt rating at 250 V AC handles larger fault energies without shattering. The change is worthwhile when the protected circuit can deliver more energy than a glass tube can safely clear.
Limited to 250 V AC and 1.5 kA interrupting
The fuse is certified for AC circuits up to 250 V and must not be used at higher voltages or on DC supplies unless separately rated. Its 1.5 kA interrupting capacity sets the maximum prospective short-circuit current it can clear safely. Circuits with higher available fault current require a fuse with a greater breaking rating.

Questions about this item
Will the 20 mm by 5 mm cylindrical body fit my existing fuse holder?
The fuse measures 20 mm long and 5 mm in diameter, matching the standard GDA cartridge size used in many 5×20 mm holders.
How do I install it without damaging the ceramic body?
Press the fuse straight into the clips using only finger pressure; twisting or prying can crack the ceramic tube.
When should I replace the fuse after it blows?
Replace it immediately with another 100 mA 250 V AC fast-acting ceramic fuse of the same 20 mm × 5 mm size to maintain the 1.5 kA interrupt rating.
