Frequently Asked Questions
What does the aR characteristic mean?
The aR (partial-range) characteristic means the fuse is designed to protect semiconductor devices by providing fast-acting interruption of short circuits while allowing for temporary overloads without nuisance tripping.
Is this fuse suitable for DC applications?
No, this fuse is rated for AC applications only, as specified in the technical specifications.
How does the striker indication system work?
The striker indication system provides a mechanical indication by releasing a striker when the fuse blows, allowing for quick visual identification of a blown fuse.
Can this fuse be used in renewable energy systems?
Yes, it is suitable for protecting power electronic components in renewable energy systems such as solar inverters.
