Five cylindrical ceramic fuses 20 mm long 5 mm diameter

Bussmann

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

SKU CH-XMS7-AJN2F

Pack of five fast-acting 250 mA ceramic fuses rated 250 V AC with 1.5 kA interrupt capacity

  • Fast-acting response protects circuits quickly
  • Ceramic body withstands high temperatures reliably
  • 5 kA interrupt rating handles fault currents safely
  • 250 V AC rating suits mains voltage applications
  • 5 mm x 20 mm cylindrical size fits standard holders

Fuse for 250 V AC circuits

The EATON BUSSMANN GDA-250MA is a ceramic-bodied fuse rated at 250 mA and 250 V AC with a 1.5 kA interrupt rating. It uses a fast-acting, non-indicating, single-element design in a 20 mm by 5 mm cylindrical body. The fuse is non-rejection type and comes in a pack of five for circuit protection tasks.

Interrupt rating and voltage match

The single specification that decides fit is the 1.5 kA interrupt rating at 250 V AC. Equipment requiring a higher breaking capacity or a different voltage class cannot use this fuse. Buyers who need a higher interrupt rating or a different voltage must select another part.

Pack of five replaces multiple spares

The five-fuse pack provides direct replacements for Bussmann GDA, S501, Littelfuse 216 and Mersen GSD series fuses. Compatible fuse blocks include the HTB series. No additional accessories or software are included.

Questions about this item

How does the 250 mA rating work once the fuse is installed in a circuit?

The fuse carries up to 250 mA continuously and opens quickly when current exceeds that value, protecting downstream components from overload.

What does the 1.5 kA interrupt rating at 250 V AC limit in practice?

It defines the maximum prospective short-circuit current the fuse can safely break at 250 V AC; circuits with higher available fault current need a higher-rated device.

What physical space and mounting does the 20 mm by 5 mm cylindrical body require?

It fits a standard 5 × 20 mm fuse holder or compatible HTB series fuse block; the ceramic body is non-rejection so it seats without a keyed notch.
