Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR (partial range) characteristic indicates that this fuse is designed to protect power semiconductors by interrupting short-circuit currents quickly while allowing normal operating currents to pass without nuisance tripping.
Can this fuse be used in DC applications?
This particular fuse is rated for AC applications only, as specified in the technical specifications. For DC applications, a fuse specifically rated for DC should be used.
How does the striker indication system work?
The integrated striker indication system provides a mechanical signal when the fuse has operated (blown), allowing for quick visual identification without removing the fuse from its holder.
Is this fuse compatible with all size 70 fuse holders?
It is compatible with size 70 fuse holders designed for bolted mounting and open slot blade connections, but always verify holder specifications to ensure proper fit and compliance.
