Frequently Asked Questions

What does the gR characteristic mean for this fuse?

The gR characteristic indicates that the fuse is a full-range semiconductor fuse designed to protect power semiconductors by clearing both overloads and short circuits rapidly.

Is the fuse suitable for DC applications?

No, this fuse is rated for AC applications only, specifically up to 690 V AC as per IEC standards.

How does the striker indication system work?

The integrated striker provides a mechanical indication by physically moving when the fuse blows, allowing for remote signalling and easy visual identification of a blown fuse.

Can this fuse be used in motor drives?

Yes, it is commonly used in industrial motor drives and power electronic circuits requiring fast and reliable semiconductor protection.
