Better check with the manufacturer about that 100KA rating. It usually is with some form of current limitation ahead of it, for a combinational rating and not a stand alone.
I have a 480V 3ph VFD that is rated for 100kA SCCR which is great
The VFD does not offer any type of current limitation, per UL508A, only a fuse or current limiting circuit breaker can do that.
What amperage is the safety contact. Put a Class CC fuse in front of it, to use table SB4.2 as a combinational rating up to 200KA.
Just my $.02
I found my easter eggs & my car keys, life is good!
