Frequently Asked Questions
What is the purpose of the thermal striker in this fuse?
The thermal striker provides a positive indication of fuse operation by triggering a mechanical signal when the fuse blows, enabling quick identification and replacement.
Is this fuse suitable for DC applications?
No, this fuse is specifically designed for AC applications at 24 kV and is not rated for DC use.
Can this fuse be used in outdoor installations?
Yes, the ceramic body and robust design make it suitable for outdoor and harsh industrial environments when installed in appropriate enclosures.
What does the indication system type 'Striker' mean?
'Striker' refers to a mechanical indicator that activates upon fuse operation, providing a visible and tactile indication that the fuse has blown.
