Rockwell Allen‑Bradley 150-C108NBD Product Description
Rockwell Allen‑Bradley 150-C108NBD is an SMC-3 smart motor soft starter for three phase AC motor control systems. This smart motor soft starter delivers 108A rated current and soft start soft stop function to meet motor inrush current limiting requirements. The compact smart motor soft starter adopts open frame cabinet mounting for installation inside motor control cabinets. This smart motor soft starter reduces mechanical impact and protects nearby contactor and PLC control modules.

150-C108NBD delivers reliable current limiting to suppress large starting surge current of AC motors. Efficient current limiting limits power grid fluctuation generated during motor startup operation. Stable current limiting prevents abnormal mechanical shock of conveyors and automation actuators. Dependable current limiting ensures stable operation of the whole automation control system.

This unit features SCR power regulation circuit with robust metal base for heat dissipation. The robust SCR power regulation circuit blocks external electromagnetic interference from entering the power control circuit. The sealed SCR power regulation circuit reduces heat accumulation and improves soft starting performance. This durable SCR power regulation circuit stays stable under cabinet vibration and temperature variation.

Rockwell Allen‑Bradley 150-C108NBD is widely matched with three phase induction motors in conveyor, fan pump and compressor control systems. It is equipped with screw power terminals for simple and secure wiring connection. It is original spare part for retrofit and maintenance of Rockwell low voltage motor soft starting systems.
