They are two different breakers. The QO230CP is just a common 2 pole 120/240volt 30amp breaker. The “CP” denotes bulk bar coded breakers.
The QO230SWN Circuit Breaker is listed as a Miniature Circuit Breaker , Switch Neutral, Plug-On, 30A, 2-Pole, 120VAC breaker. This is quite a different beast as it switches the neutral also. This must be part of a non-GMC upfitted coach as this is part of a generator switch-over system. This breaker lists for $90-$100. The Square D web page is:
http://www.schneider-electric.us/products-services/product-detail/?event=productDetail&partNumber=QO230SWN&countryCode=us
You will need the SWN breaker to replace a SWN breaker, the CP will not be the proper breaker.

Fred,
In considering what to do about this, you must remember the RV grounding
rule: "Neutral must be tied to Ground at the Power Source and ONLY at the
Power Source." Since the Onan's ground is permanently tied to the GMC, if
you don't disconnect its neutral when you switch to Shore Power, you'll have
Neutral and Ground connected on board as well as at the Shore Power pole --
a No-No which WILL cause a Shore Power GFCI to trip.

Hi Fred
You are unlikely to find that breaker at any 'big box' type store.
Try an electrical supply or wholesaler
City Electric (850-453-5552) or Dixie Electrical (850-437-5300)
If one of these don't stock it they will certainly be able to get it.
Good Luck

Ken, i already trip GFI's both at home and at RV parks that have them. it may be that i don't have the SWN in there now.
i'm going over to the coach tomorrow and remove the old one. the power went out and when i checked the breakers one of them sparked so i ran out and unplugged the power. we had to leave so i didn't have a chance to look at it further. oddly it is the left hand one that sparked. according to the drawing i have that would be the generator breaker.

Fred,
Whatever is causing the GFCI's to trip, you need to fix it. Without proper
grounding, you run too great a risk of becoming THE ground circuit for 120
VAC. While I don't have a current problem with grounding, I've started
using an external GFCI every time I plug in.

i noticed i had this problem at the first rally i went to at Chumuchla and tripped the GFCI. i started searching and found 2 faulty grounds in the 120 wiring but the GFI still tripped. i now know a new spot to look. i'll report back.
thanks,

I do work for an electrical supplier which is a Square D supplier. We do not stock but can get the QO230SWN. they are around $50 each.
Should I bring some to DuQuoin?

i just got back from checking and the problem was the breakers were not making good contact with the buss bar and were arcing. i cleaned everything up and bent the clips in tighter and all is well.
learned something from all this. should i put some Nolox on the contact points?

Another product similar to No-Alox is Penetrox.
And there are others that basically contain
powdered aluminum in a conductive grease.
