Frequently Asked Questions
What does the aR characteristic mean for this fuse?
The aR characteristic indicates that the fuse is a semiconductor fuse designed to protect against short circuits and overloads in power semiconductor devices, providing fast interruption with limited let-through energy.
How does the striker indication system work?
The striker system provides a mechanical indication of fuse operation by releasing a striker when the fuse element melts, allowing quick visual or mechanical detection of a blown fuse.
Can this fuse be used in DC circuits?
This fuse is rated for AC operation at 1250V and is not specified for DC use. For DC applications, a fuse specifically rated for DC should be selected.
What is the significance of the Omega connection?
The Omega connection design ensures a reliable and secure electrical connection, improving mechanical stability and ease of installation in industrial setups.
