Bussmann

Bussmann GDA-100MA 100mA 250VAC Fast Acting Ceramic Fuse

SKU CH-B1WJ-4QK5T

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.
