This 3-pole H-frame breaker requires 4.5 inches of mounting space on the I-Line bus, which equates to 1.5 inches per pole.
What does the SA suffix indicate for this breaker's installation?
The SA suffix means the breaker comes factory-equipped with a 120VAC shunt trip. This allows the breaker to be tripped remotely using a control voltage signal.

The YP suffix indicates that the breaker includes a factory-installed handle padlock attachment. This accessory allows the breaker handle to be locked in either the ON or OFF position.
Can I supply power to the load terminals of this breaker?
