Frequently Asked Questions
What does the 'aR' characteristic mean for this fuse?
The 'aR' characteristic indicates that the fuse is a partial-range semiconductor fuse designed to protect semiconductor devices by interrupting short-circuit currents rapidly, while allowing normal operational currents to pass without nuisance tripping.
Can this fuse be used for both AC and DC applications?
Yes, this fuse is rated for both AC and DC voltages, with a maximum rated voltage of 500V AC and 320V DC, making it versatile for various electrical systems.
How does the striker indication system work?
The striker indication system provides a mechanical signal when the fuse has operated (blown), allowing for quick visual identification and enabling remote signalling for maintenance purposes.
Is this fuse RoHS compliant?
Yes, this fuse complies with RoHS directives, ensuring it is free from hazardous substances and environmentally friendly.
