Frequently Asked Questions
What does the "aR" characteristic mean?
The "aR" characteristic indicates a high-speed fuse designed specifically for semiconductor protection, capable of interrupting high short-circuit currents rapidly to protect sensitive components.
Is this fuse suitable for DC applications?
No, this fuse is specified for AC applications only, as indicated by the AC or DC specification.
How does the striker indication system work?
The integrated striker provides a mechanical indication of fuse operation. When the fuse blows, the striker activates, enabling remote signalling or visual confirmation of fuse status for maintenance purposes.
Can this fuse be used in UL certified equipment?
Yes, the fuse is rated for 700 V AC under UL standards, making it suitable for UL certified equipment within its voltage and current ratings.
