Bussmann GDA-200MA Ceramic Fuse 200mA 250V AC 1.5kA 5 PK line protection
Pack of five 20 mm ceramic fuses rated 200 mA at 250 V AC with 1.5 kA interrupt capacity
- Fast-acting protection for sensitive circuits
- 200 mA rating matches low-current applications
- 250 V AC rating suits standard mains voltage
- 5 kA interrupt capacity clears faults safely
- Ceramic body withstands high temperatures
Purpose and fit
This pack contains five 20 mm by 5 mm cylindrical ceramic fuses rated at 200 mA and 250 V AC with a 1.5 kA interrupt rating. They suit low-current line protection in equipment that uses the GDA or 216 series form factor. Buyers needing a higher current rating or a different physical size cannot use these fuses.
Thermal and electrical behaviour
The fast-acting, single-element design opens quickly under overload to limit energy let-through. Ceramic body material withstands the heat generated during interruption at the rated 1.5 kA. No indicator flag is fitted so visual confirmation requires a continuity check. Power dissipation in normal operation stays within the limits implied by the 200 mA rating.
Accessory impact
The five-piece pack provides immediate spares for field replacement without waiting for a new order. Equivalent series markings (GDA, S501, 216, GSD) simplify cross-referencing when selecting compatible fuse blocks such as the HTB series. No additional software, mounting hardware or documentation is included.

Questions about this item
How do I install the 20 mm by 5 mm ceramic fuse into an HTB series fuse block, and what step do people often miss?
Align the cylindrical body with the HTB block clips, press firmly until both metal end caps seat fully, and verify the 200 mA rating matches the circuit; the step often missed is confirming the 1.5 kA interrupt rating suits the available fault current.
What maintenance or replacement will the GDA-200MA fuse need after it operates?
The fuse is a single-element, non-indicating device; once it interrupts a fault it must be replaced with another 200 mA, 250 V AC, 1.5 kA ceramic fuse — no resetting or partial repair is possible.
What limit appears first when the fuse carries sustained overload current?
The fast-acting element melts at 200 mA continuous current, opening the circuit before the 1.5 kA interrupt capacity at 250 V AC is ever tested.
