Is a circuit breaker rated per pole or total?

Is a circuit breaker rated per pole or total?

Product Line:
Circuit Breakers

Each pole is rated for the specified amps and the breaker is rated the same amperage total. For example, a 3p, 600 A breaker is rated 600 A at each pole, but is also rated 600 A total, not 1800 A.

The same thing is true for the breaker's interrupt rating. Any pole can have the maximum fault current that that breaker is rated for. For example a 14kA AIC rated breaker can have 14kA in any pole but the total interrupt rating will still be 14kA for a specified voltage.
