NDKB Series

The NDKB1 Series Control and Protection Switchgear (CPS) is designed for AC 50Hz circuits with a rated operational voltage up to 690V, rated operational current from 1A to 125A, controller setting current from 0.4A to 125A, and motor control power from 0.12kW to 55kW. It enables making, carrying, and breaking currents under normal conditions (including specified overload conditions), as well as making, carrying for a specified duration, and breaking currents under specified abnormal conditions (such as short circuits). The NDKB3 Series CPS is primarily applied in low-voltage distribution and motor control and protection circuits with AC 50Hz, rated operational voltage up to 690V, and rated operational current from 0.3A to 63A.
