Frequently Asked Questions
What does the "gR" designation mean for this fuse?
The "gR" classification indicates a high-speed fuse-link designed specifically for semiconductor protection, capable of interrupting high short-circuit currents rapidly to protect sensitive components.
Is this fuse suitable for DC applications?
This fuse is rated primarily for AC applications (690VAC). While it has a DC UL rating of 600V, it is generally recommended to use fuses specifically designed for DC circuits for optimal safety and performance.
How does the striker indication system work?
The striker indication system provides a mechanical signal by activating a striker mechanism when the fuse operates, allowing quick visual or electrical fault indication without removing the fuse.
Can this fuse be used in non-British Standard fuse holders?
This fuse is designed to British Standard dimensions and IEC 60269-4 compliance; it should only be used in compatible fuse holders to ensure proper fit and function.
