Frequently Asked Questions
What is the purpose of the thermal striker in this fuse?
The thermal striker provides a mechanical indication of fuse operation by tripping when the fuse blows, allowing for quick visual identification of a faulted fuse without disassembly.
Can this fuse be used in DC applications?
No, this fuse is designed for AC applications only, as specified by the AC rating of 24 kV and 16 A.
What is the breaking capacity of this fuse?
The fuse has a maximum breaking capacity of 65 kA at rated voltage, ensuring it can safely interrupt high fault currents.
Is the fuse suitable for outdoor installations?
The fuse’s ceramic body and robust design make it suitable for industrial environments; however, additional weatherproof enclosures may be required for outdoor use.
