Look on Amazon. Depending on the brand and series, they have a wide varity os Service Equipment rated "main" breakers.
You can use the tip that Carl provided, but expect to pay a lot more (double).
Any conventional electrical supply house will be able to order one. That said; The alternate way (and likely less expensive) for immediate use is to purchase the whole panel at a big box store. Remove breaker from panel and install in old. Look up bolt torque spec from mfg website and set with a torque wrench. Unless you have an odd ball panel.
I use this method for other components as well, rather than demo, replace, repair/paint. Seems a shame to throw out a perfectly good cabinet, but it saves time/$s.
SOURCE: I need to install a GFI breaker on a Baptistry.
You could install a standard GFCI in line at each component ( heater, pump & timer) or you could install AFCI breakers similar to what are required in many residential codes (provide the same protection at the panel not at the location... http://www.cpsc.gov/CPSCPUB/PUBS/afcifac8.PDF
The AFCI breakers will need to match your panel type (siemens, GE or Square-D) and the amperage/configuration.
I would install them at the lowest level (closest to the components) in the system to reduce possibility of fire in the wiring between the components and the afci breaker.

I have seen circuit breakers trip at a lower amperage. It seems that they are weak. Generally circuit breakers run with 80% load with no problem, in your case 24 amps. I would replace the circuit breaker.
SOURCE: I have 2-240V (4.2V) basebaord heaters, Need Wiring Diagram
you get 120V from any phase (black OR red) to neutral
you get 240V from phase to phase (between black and red) and in this scenario you don't need the white wire.
So for you, connect the black to 1 pole of the breaker and the red to the other pole, connect the green wire to the ground strip and you are done.
A white wire is NEVER connected to a circuit breaker anyway, it is a grounded wire, it would be like connecting a green wire to a black wire, bad idea.
the National electrical code specifies red and black wire color for 240VAC circuits.
As Ask Hank mentionned, nothing wrong with 10/3 wire.
