Frequently Asked Questions
What does time-lag mean for this fuse?
Time-lag means the fuse can tolerate short-term current surges without blowing, allowing for temporary inrush currents common in motors and transformers.
Is this fuse suitable for DC applications?
No, this fuse is rated specifically for AC applications up to 250V as per the technical specifications.
How do I know if the fuse has blown?
The glass body allows visual inspection; a broken filament inside indicates the fuse has blown and needs replacement.
Can this fuse be used in high vibration environments?
While the fuse is robust, it is recommended to verify mounting and environmental conditions to ensure secure installation in high vibration settings.
