Frequently Asked Questions

What does the gR speed/characteristic mean?

The gR characteristic indicates a high-speed fuse designed to protect semiconductor devices by quickly interrupting short-circuit currents while allowing transient overloads. It ensures minimal let-through energy to safeguard sensitive components.

Is this fuse suitable for AC applications?

No, this fuse is specifically designed for DC applications up to 750 VDC. For AC applications, a different fuse type with appropriate ratings should be selected.

What is the purpose of the striker indication system?

The striker indication system provides a visual signal when the fuse has operated (blown), allowing quick identification of faulted circuits without disassembly.

Can this fuse be used in renewable energy systems?

Yes, it is ideal for renewable energy applications such as solar and wind power systems where reliable DC protection is critical.
