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 clearing short-circuits rapidly but allows for limited overload currents without blowing, providing selective protection.
Can this fuse be used in DC applications?
This fuse is rated for AC applications only, as specified in the technical specifications. It is not suitable for DC circuits.
How does the striker indication system work?
The striker mechanism provides a mechanical indication by tripping and producing a visible or tactile signal when the fuse has operated, allowing quick identification of a blown fuse without disassembly.
What type of mounting does this fuse require?
This fuse uses bolted mounting with DIN 110 blade terminals, ensuring a secure and reliable connection in industrial fuse holders designed for Size 73 fuses.
