Will a DC circuit breaker trip due to high voltage?
Circuit breakers do not "know" the voltage of the circuit they are used in, so cannot trip based on that voltage - they only trip on over-current.

However, they are designed and rated to operate correctly (trip cleanly) only up to a certain voltage - using a 32 volt breaker on a 120 volt circuit may result in the breaker arcing when it trips (likewise, using a DC-rated breaker on an AC circuit, or vice versa, may result in faulty operation.)

(GFCI and AFCI breakers may be more sensitive to voltage than normal breakers)
