Bussmann GMW-1-1/2 – Frequently Asked Questions

1) What amp ratings can I get the Bussmann GMW fuse in?
The GMW series runs from very small instrument-level ratings up through 5A. Orderable ratings are 0.016A (GMW-1/64), 0.1A (GMW-1/10), 0.5A (GMW-1/2), 1A (GMW-1), 1.5A (GMW-1-1/2), 2A (GMW-2), 3A (GMW-3), 4A (GMW-4) and 5A (GMW-5). The part number carries the rating as a fraction or whole number, so order by the exact MPN to avoid getting a 1/2A where you wanted a 5A.
2) Can I use a GMW fuse on a 250 volt control circuit?
No. The GMW is rated 125V, so keep it on circuits at or below that. Applying a 125V fuse on a 250V circuit risks the fuse failing to clear a fault safely. For 240V control work you need a fuse with a voltage rating at least matching the circuit.
3) What fault current can the Bussmann GMW fuse interrupt?
35 AIC. That is a low interrupting rating, which is normal for a small specialty electronic fuse and fine on transformer-limited control and instrument circuits. If your available fault current at the fuse location is higher than 35 amps, this is the wrong fuse and you need a higher-interrupting device.
4) How fast does the GMW fuse clear an overload?
Its published characteristic is 4 hours minimum at 100% of rating and 10 seconds maximum at 200%. In practice that means it will carry rated current indefinitely but opens quickly on a genuine overload, which is what you want protecting sensitive electronics and instrumentation rather than a motor with inrush.
5) Is the GMW fast-acting or time-delay?
Fast-acting. With 10 seconds maximum clearing at 200% of rating, it responds quickly and is not intended for loads with a heavy inrush, like transformers or motors. Use it on control circuits, instrumentation and electronic equipment where a quick open protects the downstream device.
6) Does the Bussmann GMW fuse have a blown-fuse indicator?
No, the GMW is a non-indicating fuse. There is no pop-up pin or LED flag, so troubleshooting means pulling the fuse and testing continuity. If your panel design depends on visual identification of an open fuse, specify an indicating type instead.
7) How do Bussmann GMW fuses come packaged for stocking?
Standard packaging, sold by amp rating with a distinct part number and UPC for each, from GMW-1/64 through GMW-5. Each fuse weighs .2 lb as catalogued. For a service truck or MRO crib, stocking the common 1A, 2A, 3A and 5A ratings covers most control-circuit work.
