Frequently Asked Questions
What does the aM characteristic mean for this fuse?
The aM characteristic indicates that the fuse is designed to protect motor circuits by allowing short-duration current surges typical during motor starting, while providing reliable protection against overloads and short-circuits.
How does the double indicator system work?
The double indicator provides a clear visual signal on both ends of the fuse-link, showing whether the fuse has operated (blown), which simplifies maintenance and reduces downtime.
Can this fuse-link be used in DC applications?
No, this particular fuse-link is rated for AC applications only, as specified in its technical specifications.
What safety features does the live tag design provide?
Live tags allow safe and easy connection and disconnection of the fuse without exposure to live parts, reducing the risk of electrical shock during handling.
