Frequently Asked Questions
What does the aR speed/characteristic mean?
The aR rating indicates an "anti-restart" fuse characteristic designed to protect semiconductor devices by providing fast and selective interruption of short-circuit currents.
Is the fuse suitable for DC applications?
No, this fuse is specified for AC applications only, with a rated voltage of 690 VAC.
How does the integrated striker indication system work?
The striker provides a mechanical indication when the fuse has blown, allowing for quick visual checks and enabling remote signalling systems to detect fuse status.
Can this fuse be used in switchgear with different mounting types?
This fuse is designed for bolted mounting with L bracket terminals; ensure compatibility with your equipment before installation.
