Frequently Asked Questions
What does the aM characteristic mean?
The aM characteristic indicates that the fuse is designed for motor circuit protection, allowing short-time current surges during motor start-up without blowing, but providing rapid interruption during short circuits.
Is this fuse suitable for DC applications?
No, this fuse-link is rated for AC applications up to 500 V and is not suitable for DC circuits.
How does the striker indication system work?
The striker mechanism provides a visual indication when the fuse has operated by ejecting a striker pin, which can also be used for remote signalling.
Can this fuse be used in existing NH fuse bases?
Yes, the NH3 size and 69 mm body width ensure compatibility with standard NH fuse bases designed for this size.
