FAE Expert Insights
"The FD300-1000 is ideal for smaller EV and energy storage systems where 400A is not needed. The 300A rating is perfect for compact battery packs and auxiliary systems. I often recommend this fuse for commercial EV applications where space is at a premium. The same reliable DC arc quenching as the larger FD400 ensures safe operation."

Frequently Asked Questions
What is the difference between FD300 and FD400?
The main difference is current rating - FD300 is rated for 300A continuous current while FD400 is rated for 400A. Both have the same 1000VDC voltage rating and 100kA breaking capacity. The FD300 is more compact and suitable for smaller systems where 300A is sufficient.
Choose FD300 for systems up to 250A continuous. Choose FD400 for systems up to 350A continuous.
