Frequently Asked Questions
What does the 'aR' characteristic mean?
The 'aR' characteristic indicates a semiconductor protection fuse that provides partial-range protection, designed specifically to protect power semiconductors by interrupting short-circuit currents rapidly.
How does the striker indication system work?
The striker is a mechanical indicator that activates when the fuse operates, allowing remote visual or electrical signalling to alert maintenance personnel of fuse failure.
Can this fuse be used on DC circuits?
No, this fuse is rated for AC applications only, as indicated by the 'AC or DC' specification.
What is the significance of the breaking capacity?
The breaking capacity of 200 kA means the fuse can safely interrupt fault currents up to 200,000 amperes without damage, ensuring protection under high fault conditions.
