Frequently Asked Questions
What does the 'aR' speed characteristic mean?
The 'aR' (advanced semiconductor) speed characteristic means the fuse is designed to provide fast-acting protection specifically for semiconductor devices, quickly interrupting fault currents to prevent damage.
Is this fuse suitable for DC applications?
While the fuse has a rated DC voltage of 250 V, it is primarily designed and UL approved for AC applications. Please consult technical documentation for specific DC use cases.
How does the integrated striker indication work?
The integrated striker provides a mechanical indication of fuse operation, allowing remote signalling systems to detect when the fuse has blown, facilitating faster maintenance response.
Can this fuse be used in motor drive protection?
Yes, this fuse is suitable for protecting power semiconductors in industrial motor drives and inverters, offering reliable fast-acting protection.
