Frequently Asked Questions
What does the aR characteristic mean?
The aR (partial range) characteristic indicates that the fuse is designed for semiconductor protection, interrupting short-circuit currents quickly while allowing for certain overload conditions without blowing.
Is this fuse suitable for DC applications?
No, this fuse is rated for AC applications only as specified in the technical specifications.
How does the striker indication system work?
The striker indication system provides a mechanical indication of fuse operation by triggering a visible striker when the fuse blows, allowing quick identification of a blown fuse without disassembly.
Can this fuse be used in both IEC and UL rated equipment?
Yes, this fuse meets both IEC and UL voltage ratings (690VAC IEC and 700VAC UL), making it suitable for equipment compliant with either standard.
