No. Circuit breakers and overvoltage and undervoltage protectors provide different protections. Circuit breakers primarily interrupt short-circuit currents, tripping to protect equipment when a short-circuit occurs. Overvoltage and undervoltage protectors, on the other hand, operate when they detect system voltage anomalies (over- or under-voltage). While the two functions complement each other, they cannot replace each other.
