Frequently Asked Questions
What does the gR characteristic mean?
The gR characteristic indicates a full-range semiconductor fuse designed to protect semiconductor devices by clearing both overload and short-circuit faults rapidly.
Is this fuse-link suitable for DC applications?
This fuse-link is rated primarily for AC applications at 690V. While it has a DC rated voltage of 700V UL, confirm suitability with your specific DC application requirements before use.
Can this fuse be used in a 100A circuit?
No, this fuse is rated for 75A. Using it in a 100A circuit risks nuisance blowing or insufficient protection. Select a fuse with an appropriate ampere rating for your circuit.
What mounting options are available?
This fuse-link is designed for bolted mounting using L bracket terminals for secure and stable connections.
