    • A novel contact opening mechanism has been developed using a piezoelectric actuator to open the contacts in a low contact opening velocity circuit breaker. The arc control on the contacts is critical for a successful current interruption 10,000-100,000 A. in low voltage 250 Volts devices. Previous work has shown how arc root commutation from the contact region into the arc…
