Frequently Asked Questions

What does the aR characteristic mean for this fuse?

The aR characteristic indicates a high-speed fuse designed specifically for semiconductor protection, allowing rapid interruption of fault currents to protect sensitive devices.

Is this fuse suitable for DC applications?

No, this particular fuse is rated for AC applications only, as indicated in the technical specifications.

How does the striker indication system work?

The striker provides a mechanical indication by triggering a visible or remote signal when the fuse operates, enabling quick fault identification.

Can this fuse be used in systems with voltages higher than 700V?

No, the fuse is rated for a maximum AC voltage of 700V UL and 690V IEC. Using it beyond these limits is not recommended.
