Five glass cylinder fuses with metal end caps

Bussmann

Bussmann GDB-200MA 200mA 250V AC 35A Glass Fuse 5 PK

SKU CH-RHJ7-M9EE3

Fast-acting glass fuse rated 200 mA at 250 V AC with a 35 A interrupt rating, supplied in a pack of five

  • Fast-acting protection clears faults quickly
  • 35 A interrupt rating handles short-circuit surges
  • 200 mA at 250 V AC suits low-current circuits
  • 20 mm × 5 mm glass body fits standard holders
  • Pack of five fuses supports multiple installations

Five-pack of 200 mA glass fuses

This pack contains five GDB-series glass fuses rated at 200 mA and 250 V AC. They are designed for circuit protection in low-current equipment and control circuits. The cylindrical 20 mm by 5 mm body fits standard fuse holders and blocks. Each fuse is fast-acting and non-rejection type.

Fast-acting glass body with 35 A interrupt rating

The glass construction allows visual inspection of the element after a fault. In normal operation the fuse runs cool and silent because it carries only its rated current. When a fault occurs the single element opens quickly and the 35 A interrupt rating at 250 V AC safely contains the energy. No active cooling or noise is produced.

20 mm by 5 mm cylindrical glass fuse

The critical specification is the physical size combined with the 200 mA rating; only holders and blocks that accept a 20 mm by 5 mm glass cartridge will work. Buyers who need a different current rating, a ceramic body or a rejection-style fuse cannot use this part.

Questions about this item

How do I install the 5 mm diameter glass fuse into a compatible holder, and what step is often missed?

Insert the 20 mm long cylindrical body straight into an HTB series fuse block until both metal end caps seat fully; the step often missed is verifying the holder is rated for 250 V AC and 35 A interrupt capacity before closing the circuit.

What maintenance or replacement will the GDB-200MA fuse need after it operates?

The fuse is a single-element, non-rejection device; once it interrupts a fault at 35 A it must be replaced with another 200 mA, 250 V AC unit from the 5-pack — no resetting or partial repair is possible.

What limit appears first when the fuse carries continuous current near its 200 mA rating?

The fast-acting element reaches its melting point and opens the circuit; sustained current at or above 200 mA causes the fuse to blow, which is its intended protective function.
