The Allen-Bradley 150-C25NBD is a 25 A SMC-3 soft starter (soft motor controller) designed for open-type, three-wire control of 3-phase motors. It is rated for line voltages of 380–460 V AC at 50/60 Hz, with a 100–240 V AC control supply, making it suitable for use with line-connected motors in industrial equipment. As part of the SMC-3 family, this model provides reduced-voltage starting to limit inrush current and torque during ramp-up. The 150-C25NBD carries a 25 A current rating for 3-phase loads up to 460 V AC and is intended for integration in standard motor-control circuits in manufacturing and processing environments.
