NDC1-4000/4500

The NDC1-4000/4500 AC Contactor (hereinafter referred to as the contactor) is primarily used in AC-1 utilization category circuits with AC 50Hz (or 60Hz), a rated operational voltage of 1140V, and a conventional free-air thermal current of 4000A or 4500A. It is designed for making and breaking load circuits with currents below 1700A, controlling resistive, non-inductive, and slightly inductive loads, as well as power distribution circuits. Key application scenarios include wind power converters, inverter bypass, and soft starter bypass.
