Yes. The rated voltage currently required in industrial-use CBs is 440, 690 volts or higher. Compare those numbers to the 400V upper limit between phases for residential MCBs. Reference ambient temperatures are 30°C for households. The same goes for impulse withstand voltage (Uimp). IEC 60898-1 requires 4kV, in line with the use for final circuits. Whereas for industrial circuit-breakers, usual values of Uimp is 6 or 8kV, in line with the position of the circuit-breaker, at the origin of the installation.
