Frequently Asked Questions
What does the 'aR' characteristic mean for this fuse?
The 'aR' characteristic indicates that this is a partial range high-speed fuse designed to protect semiconductor devices by interrupting short-circuit and overload currents quickly, but it does not protect against all overload conditions.
Is this fuse suitable for DC applications?
No, this fuse is rated for AC applications only, as indicated in the technical specifications.
What is the purpose of the striker indication system?
The striker provides a visual indication when the fuse has operated (blown), allowing for quick identification and replacement without the need for electrical testing.
Can this fuse be used in international installations?
Yes, it complies with both IEC 690VAC and UL 700VAC standards, making it suitable for use in various international electrical systems.
