Frequently Asked Questions
What does the aR characteristic mean?
The aR (partial range) characteristic indicates that the fuse is designed to protect semiconductor devices by interrupting short-circuits quickly while allowing normal operational currents to pass without nuisance blowing.
Is this fuse suitable for DC applications?
No, this fuse-link is rated for AC applications only, as specified in the technical specifications.
What is the breaking capacity of this fuse?
The fuse has a maximum breaking capacity of 200 kA at rated voltage, ensuring it can safely interrupt high fault currents.
Can this fuse be used in a 700V system?
Yes, the fuse is rated for 700V AC under UL standards and 690V AC under IEC standards, making it suitable for systems up to these voltages.
