Frequently Asked Questions
What does the gR characteristic mean?
The gR characteristic indicates that the fuse is a full-range semiconductor fuse designed to protect power semiconductors and related circuits by providing high-speed interruption of overloads and short circuits.
Is this fuse suitable for DC applications?
No, this fuse is specified for AC applications only, rated at 690 V AC. For DC applications, a fuse rated specifically for DC voltage should be used.
How does the striker indication system work?
The striker indication system provides a visual and mechanical indication when the fuse has blown, allowing quick and easy identification of faulted fuses without disassembly.
Can this fuse be used in renewable energy systems?
Yes, due to its high breaking capacity and fast response, this fuse is suitable for protecting semiconductor devices in renewable energy systems such as solar inverters and wind turbines.
