Square D Breaker and SKM

[kjjack]

I've got information given to me off of a 480V MCC main breaker as a
Square D
PEG-16
1600A
with ground fault pickup/delay settings
with 'amp X rating plug' and short time pickup settings
I need to find time-current curve info for this breaker for coordination using SKM PowerTools.

Have you tried asking your local Square D sales engineer? They can get this data for you.

kjjack,

I use SKM quite extensively, and the "PE" style breaker is available in the database. "G" refers to ground fault, which is also in the ground fault database.

mpparent, thank you and everyone else for their responses. Would I model this in SKM as two separate breakers, i.e. a "PE" and a "G" breaker?

kjjack,

It depends on what version you have. The latest version allows you to assign multiple "identities" to one breaker. In the older version, you have to place two breakers, then assign one with the LSI characteristics(or LI, or LS depending on your breaker), and one with the ground fault characteristics. If you have the old, you would model one breaker as the "PE", and the other as the "PEG".
