Frequently Asked Questions
What does the 'aR' speed characteristic mean?
The 'aR' designation indicates a high-speed fuse characteristic designed to protect semiconductor devices by interrupting fault currents rapidly, minimising damage.
Can this fuse be used in DC circuits?
This fuse is rated for AC applications only, as specified in the technical specifications.
How does the striker indication system work?
The striker mechanism provides a visual indication by releasing a striker when the fuse operates, allowing quick identification of a blown fuse without disassembly.
Is this fuse suitable for retrofitting older equipment?
Yes, provided the equipment uses the same fuse size (2x73) and mounting method (bolted), and the voltage and current ratings match the application requirements.
