Hello,
How do I model a Fused circuit breaker in SKM? The breaker is 800A Cutler-Hammer DSL-206.

Looks like you have an Eaton Magnum DS with current limiters. Just put the breaker and current limiting fuses in series with each other. Here is an example but I don't know exactly which breaker you have or what the amp rating is of the limiter so I just somewhat randomly picked them. This is in SKM. Attachment:

Man, I think I have modeled it incorrectly. I thought it was fuse then breaker.

File comment: It's cb 6, 7, & the main circuit breaker.

Not sure why it would make any difference. I have a customer with this type of gear and have the shop drawings with factory one-lines I can check but not until Thursday.
You might be right. I can't remember if it's breaker then fuse or fuse then breaker. Again though, makes no difference for anything downstream.

Looks like you probably are correct fuse then breaker if I'm seeing this pic correctly. Attachment:

Bus then limiter then breaker according to some old shops I had. You were correct: Attachment:
