Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR (partial range) characteristic means the fuse is designed to protect power semiconductors by interrupting short-circuit and overload currents quickly, but it does not protect against all overloads, focusing on high-speed fault clearance.
Is this fuse suitable for DC applications?
No, this particular fuse is rated for AC applications only, as indicated by its AC voltage ratings and specifications.
How does the striker indication system work?
The striker indication system provides a visual signal when the fuse has operated (blown), allowing for quick identification and replacement without additional testing equipment.
Can this fuse be used in renewable energy systems?
Yes, it is suitable for protecting power semiconductors in renewable energy inverters and converters, such as solar power systems, due to its high-speed interruption capability and voltage ratings.
