Frequently Asked Questions

What does the 'aR' speed characteristic mean?

The 'aR' characteristic indicates a high-speed fuse designed specifically for protecting semiconductor devices, providing rapid interruption of short circuits while allowing for temporary overloads.

Is this fuse suitable for DC applications?

No, the FR14AR69V10T is rated for AC applications only, as specified in the technical specifications.

How does the striker indication system work?

The integrated striker mechanism triggers a mechanical indicator when the fuse operates, allowing remote signalling devices to detect fuse failure for prompt maintenance.

Can this fuse be used in solar inverter protection?

Yes, its high breaking capacity and fast-acting characteristic make it suitable for protecting power electronics in renewable energy systems such as solar inverters.
