Frequently Asked Questions
What is the purpose of the thermal striker in this fuse?
The thermal striker provides a clear mechanical indication when the fuse has operated, allowing for quick identification of faulted circuits without the need for visual inspection of the fuse element.
Can this fuse be used in DC applications?
No, this fuse is specified for AC applications only, as indicated by its AC rating and IEC standards compliance.
What is the significance of the 65 kA breaking capacity?
The 65 kA breaking capacity means the fuse can safely interrupt fault currents up to 65,000 amperes without damage, ensuring protection in high fault current environments.
Is the fuse reusable after operation?
No, once the fuse has operated (blown), it must be replaced to restore protection.
