Bussmann GMT-4A – Frequently Asked Questions

1) Is the Bussmann GMT-4A an alarm-indicating fuse that pops a flag when it blows?
No. The GMT-4A is non-indicating. If you need a fuse that throws a mechanical indicator or trips a fuse-fail alarm circuit when it opens, this is the wrong part and you want the indicating version of the GMT in the same amperage.
2) What does the white/brown color code on a GMT fuse mean?
On the GMT platform the colored flag tells you the amp rating at a glance without pulling the fuse and reading the barrel. White/brown is the 4A marking, so a tech walking a cross-connect bay can confirm the right value is in the clip before touching anything.
3) Fast-acting or time-delay for telecom equipment protection?
The GMT-4A is fast-acting, which is what telecom and low-voltage signal circuits normally call for. These loads have little inrush, and the electronics behind them want the fuse to clear quickly on a fault. Time-delay fuses are for motor or transformer inrush, not cross-connect and data panel protection.
4) What size is the Bussmann GMT-4A fuse body?
It measures .78 x .62 x .11 in and weighs .1 lb, which is the standard GMT footprint for drop-in replacement in existing GMT fuse blocks and alarm panels.
5) Will the GMT-4A terminals corrode in a damp remote terminal cabinet?
The terminals are tin-plated beryllium copper, chosen for corrosion resistance and stable contact pressure in the clip. That combination holds up better than plain brass in cabinets that see humidity swings.
6) Does the Bussmann GMT-4A carry any compliance marking for a European or export build?
It is CE marked. That is the compliance marking stated for the GMT-4A.
