Frequently Asked Questions
What does the aR speed characteristic mean?
The aR (partial range) characteristic indicates that the fuse is designed to protect semiconductor devices by clearing short-circuits quickly but not overloads, providing high-speed protection for sensitive components.
Is this fuse suitable for DC applications?
No, this fuse is rated for AC applications only, as specified in the technical specifications.
Can this fuse be used as a direct replacement for other 17x49 fuses?
Yes, provided the electrical ratings and characteristics match the system requirements. Always verify compatibility with your equipment 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.
