Frequently Asked Questions
What does the 'aR' characteristic mean for this fuse?
The 'aR' characteristic indicates that the fuse is a semiconductor protection fuse designed to clear short circuits rapidly while allowing for normal transient currents, providing selective protection for power semiconductors.
Can this fuse be used in DC applications?
No, this fuse is rated specifically for AC applications up to 1500V and is not suitable for DC circuits.
How does the striker indication system work?
The striker indication system provides a mechanical signal by ejecting a striker when the fuse operates, allowing for quick visual and remote indication of a blown fuse.
Is this fuse compatible with standard Size 91 fuse holders?
Yes, it is designed to fit Size 91 fuse holders with metric threaded flush ends for bolted mounting.
