Five small cylindrical ceramic fuses with metal end caps

Bussmann

Bussmann GDA-63MA Ceramic Fuse 63mA 250V 1.5kA 5 PK

SKU CH-RVMK-XN7GN

Pack of five 63 mA, 250 V fast-acting ceramic fuses with 1.5 kA interrupt rating

  • Fast-acting protection clears faults quickly
  • 63 mA rating suits low-current circuits
  • 250 V AC voltage handles mains-level supplies
  • Ceramic body withstands high interrupt energy
  • Pack of five provides spare fuses

Bussmann GDA-63MA Ceramic Fuse Pack

This pack contains five fast-acting ceramic fuses rated at 63mA and 250V AC. They suit technicians and engineers protecting low-current circuits in test equipment, instrumentation or industrial controls. Buyers needing higher amperage ratings or indicating fuses for visual fault detection should look elsewhere.

Thermal and Electrical Behaviour

The ceramic body withstands the heat generated during a fault interruption rated at 1.5kA. Fast-acting elements open quickly to limit energy let-through without sustained arcing. Normal operation produces no audible noise and negligible power loss across the element.

Equivalent Series and Compatibility

The fuses cross-reference to Bussmann S501, Littelfuse 216 and Mersen GSD series for direct replacement. They fit compatible HTB fuse blocks designed for the 20mm by 5mm cylindrical form factor. No software or additional accessories are included with this five-pack.

Questions about this item

How do I install the GDA-63MA fuse in a 20 mm by 5 mm holder without damaging the ceramic body?

Align the cylindrical fuse with the clips, press straight in until both metal end caps seat fully, and avoid twisting the ceramic tube during insertion.

What replacement interval applies to a fast-acting 63 mA ceramic fuse after a fault event?

Replace the fuse immediately after it interrupts a circuit; the single-element design cannot be reset and shows no visual indication when blown.

At what sustained current level will the 1.5 kA interrupt rating become the limiting factor?

The 1.5 kA rating limits the maximum prospective short-circuit current the fuse can safely clear at 250 V AC.
