Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR characteristic indicates that the fuse is a partial range semiconductor fuse designed to protect against overloads and short circuits in semiconductor devices, providing fast interruption of fault currents.
Can this fuse be used in DC applications?
This fuse is rated for AC applications only, as specified in the technical specifications. For DC applications, a fuse with a suitable DC rating should be selected.
How does the striker indication system work?
The striker is a mechanical indicator that pops out when the fuse element melts, providing a clear visual indication that the fuse has blown and needs replacement.
What is the significance of the rated voltage differences between IEC and UL?
The fuse is certified to IEC at 1250V AC and UL at 1300V AC, reflecting different testing standards and approvals in international markets, ensuring safe operation under those voltage limits.
