Bussmann GBA-1/2 – Frequently Asked Questions
1) Will the Bussmann GBA-1/2 fit a standard 1/4 x 1-1/4 inch fuse holder?
Yes. The GBA-1/2 is a .25 inch diameter glass-size ferrule fuse measuring 1.25 inches long, with ferrule end X ferrule end connections, so it drops into any standard ferrule-style clip holder or fuse block cut for a 1/4 x 1-1/4 inch cartridge.
2) What amp rating is a GBA-1/2 fuse, and what circuits is it meant for?
The GBA-1/2 is a 500 mA (half-amp) fast-acting fuse rated 125V. It is intended for control circuits and electronic circuits, which is where you see it in industrial control panels, OEM panel wiring, and low-voltage device protection.
3) Can I use a 125V GBA-1/2 fuse on a 240V control circuit?
No. The GBA-1/2 is rated 125V, so it must not be applied above that. For a 240V or 250V control circuit you need a fuse rated at or above the circuit voltage; a 125V fuse may not clear the arc safely at higher voltage.
4) Can I tell by looking whether a GBA-1/2 fuse has blown?
Not from an external indicator. The GBA-1/2 is specified as a non-indicating fuse, so there is no pop-out flag or lamp to signal an open element. Check it with a meter on continuity, or use an indicating-style fuse holder if you need visual fault identification on the panel.
5) Does the GBA-1/2 come as a single fuse or in a box of 100?
It is supplied in a standard pack of 100, which is how MRO and panel-build buyers usually stock a half-amp control fuse. Body construction is a fiber tube with nickel-plated brass endcaps, so the ferrules resist corrosion in storage and in the holder clips.
6) How much does a box of Bussmann GBA-1/2 fuses weigh for shipping?
Listed product weight is .86 LB for the 100-count pack, so it ships as a small parcel item alongside other panel components.
