Bussmann GMA-1-R – Frequently Asked Questions

1) Is the GMA fast-acting or time-delay, and will it nuisance-trip on motor inrush?
Fast-acting. It clears in 60 minutes maximum at 135 percent of rating and 2 minutes maximum at 200 percent, which is sized for electronics and low-inrush loads. For transformer or motor inrush you want a time-delay fuse instead, not the GMA.
2) What amp ratings does the Bussmann GMA glass fuse come in?
Two ratings are offered: 1 amp (GMA-1-R) and 3 amp (GMA-3-R). Pick the rating against the circuit's steady load, not the supply, since this is a fast-acting fuse with no inrush tolerance built in.
3) What is the interrupting rating on the Bussmann GMA fuse?
35A at 250VAC, and 10 kAIC at 125VAC. That 10 kAIC figure is the one to quote when a panel spec calls for a minimum interrupting capacity on the branch protection.
4) Can you tell if a GMA fuse is blown without pulling it?
Not by an indicator. The GMA is non-indicating, so there is no pop-up pin or LED flag. The upside of the glass tube is that you can usually see the open element through the body, but for panels where you need visual status at a glance, specify an indicating fuse or an indicating holder.
5) Do Bussmann GMA fuses meet RoHS for equipment shipping into Europe?
The GMA series is RoHS compliant and CE marked, which covers the two things an OEM procurement team usually has to document for export builds. The 32VDC rating is self certified.
6) Will GMA fuses corrode in a humid panel or outdoor enclosure?
The endcaps are nickel-plated brass on a glass tube body, which holds up better against contact corrosion than bare brass in damp enclosures. The ferrule ends seat in standard clip-style holders, so plating condition matters for keeping contact resistance low over time.
