Frequently Asked Questions
What does the 'aM' speed/characteristic mean?
The 'aM' characteristic indicates that the fuse is specifically designed for motor protection, providing selective tripping for motor circuits while allowing temporary overloads during motor start-up.
Can this fuse-link be used in DC applications?
No, this fuse-link is rated for AC applications only, as specified under the 'AC or DC' technical specification.
How do the double indicators work?
The double indicator system provides a clear visual signal when the fuse has blown, enhancing safety and reducing downtime during maintenance.
What is the significance of live tags?
Live tags allow for safe handling and installation of the fuse-link without direct contact with live parts, improving operator safety.
