Greetings to all. I hope this finds you well. Once again the subject of SCCR has come up. I have struggled for years to find a document or someone who can explain this to me. The bottom line is I need to know how I would determine the SCCR for my product. In one case in particular I am currently working on, it is a 3 phase motor-driven industrial device. It draws less than 8 amps at 230V. Internal to the device, we have three "CC" type fuses with a SCCR of 200KA. However, ahead of that we have a lockout/tagout disconnect device that is only rated 10KA SCCR.
How exactly can I determine the SCCR of my device? Thank you all.
