Frequently Asked Questions
What does the 'gR' characteristic mean for this fuse-link?
The 'gR' characteristic indicates that the fuse-link provides full-range protection for semiconductor devices, capable of interrupting both overload and short-circuit currents with fast response times.
Is this fuse suitable for DC applications?
This fuse-link is primarily designed for AC applications up to 690V IEC and 700V UL. While it has a rated DC voltage of 700V UL, suitability for DC circuits should be confirmed based on specific application requirements and standards.
Can I use this fuse-link in a non-UL certified system?
Yes, the BS17US69V40 meets British and IEC standards as well, making it suitable for systems without UL certification, provided the electrical ratings match your system requirements.
