Frequently Asked Questions
What does the aR speed/characteristic mean?
The aR (partial range) characteristic indicates that the fuse is designed for protection of semiconductor devices, providing high-speed interruption for short circuit faults while allowing for temporary overloads.
Is the striker indication system resettable?
No, the striker indication system provides a one-time mechanical indication of fuse operation that must be manually reset or replaced after a fault.
Can this fuse be used in DC applications?
This fuse is rated for AC use only and should not be used in DC circuits.
What is the significance of the breaking capacity of 200 kA?
The breaking capacity indicates the maximum fault current the fuse can safely interrupt without damage, ensuring reliable protection in high fault current environments.
