Frequently Asked Questions

What does the aR characteristic mean?

The aR (partial range) characteristic indicates that this fuse is designed for semiconductor protection, offering rapid interruption of short-circuits while allowing for inrush currents typical in power electronics.

Is this fuse suitable for DC applications?

Yes, this fuse is rated for both AC and DC voltages, with a maximum DC voltage rating of 450V, making it suitable for many DC semiconductor protection applications.

How does the striker indication system work?

The integrated striker provides a mechanical indication of fuse operation by releasing a visible striker when the fuse blows, enabling quick and easy fault identification without disassembly.

Can this fuse be used in standard NH fuse holders?

Yes, it is designed to fit NH 00 fuse holders with DIN 80 blade terminations, ensuring compatibility with standard mounting hardware.
