Frequently Asked Questions
What does the "gR" designation mean for this fuse?
The "gR" designation indicates a full-range semiconductor fuse, designed to protect power semiconductors by interrupting all overcurrents, including short-circuits and overloads.
Can this fuse be used in DC applications?
This fuse is rated primarily for AC applications up to 690VAC. While it has a DC UL rating of 600 V, it is recommended to consult system requirements before use in DC circuits.
How does the striker indication system work?
The integrated striker provides a mechanical indication by triggering a visible or audible signal when the fuse operates, allowing for quick identification of a blown fuse without disassembly.
What is the breaking capacity of this fuse?
The fuse has an AC maximum breaking capacity of 200 kA, ensuring it can safely interrupt very high fault currents without damage.
Is this fuse compatible with standard 17x49 fuse holders?
Yes, this fuse is designed to fit standard 17x49 fuse holders with bolted mounting and copper L bracket terminals.
