Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR (partial range) characteristic means the fuse is designed to protect semiconductor devices by interrupting short-circuit currents while allowing harmless overloads to pass without blowing.
Can this fuse be used in DC applications?
This fuse is rated for AC applications only, as specified in the technical specifications.
How does the striker indication system work?
The striker provides a mechanical indication by releasing a visible signal when the fuse operates, allowing quick identification of a blown fuse without disassembly.
What type of mounting does this fuse require?
This fuse is designed for bolted mounting, ensuring a secure and stable connection in industrial setups.
