A set of contact inputs allows integration with an automatic transfer switch (ATS). When paired with Leviton 2nd Gen smart circuit breakers, it provides unparalleled control of your home's electrical system, including alerts for circuit breaker trips, notifications for unusual activity, and the ability to remotely control and schedule circuit breakers.
