Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR (partial range) characteristic means the fuse is designed to protect power semiconductor devices by interrupting short-circuit and overload currents quickly, but it does not protect against all overload conditions.
Can this fuse be used in DC applications?
No, this fuse is rated for AC applications only, as indicated by its specifications.
What is the purpose of the double indicator on this fuse?
The double indicator provides a clear visual signal when the fuse has operated, allowing for quick identification and replacement, which helps minimise downtime.
Is this fuse compliant with international standards?
Yes, it is certified to IEC and UL standards, ensuring it meets rigorous safety and performance requirements.
