I am running a MWBC to a garage. What is a recommended 2 pole swiitch?
I recall that not all 2 pole switches are listed for 240 volts.

Use an AC disconnect it's cheap and works good for the purpose. I even use them when it's a 60a run to a building with a main lug panel inside. Over 60a I use a 100 main breaker panel
Only downside to that is its size. Sometimes a simple switch is more convenient to integrate. (Forgive my captain obvious here)
