Hello,
Thanks for your explanation. It’s a very good synthesis. Therefore, I have 3 questions.
Firstly, you mentionned you’re trying to use fuses only with small loads because the protection of phase missing is not assured by the standard fuses. But Schneider sales engineer mentionned me we can use an electronic equipment (fuse monitor) to detect the phase failure. Is it expensive? Did you already used?
Secondly, you mentionned also problem to have fuses above 630A. Do fuse manufacturers range limit their range at 630A? Which manufacturers can I choose?
And Finally, why do you prefer to use fuses to protect capacitors? I have some applications where I have to protect capacitors. So, I’m very interesting to have your position.
Another question, I’ve also some customers who are using Drives. I was thinking to use fuse UR for these appplications. What is your position on this topic?
Best regards,
FredG
