Product Overview
The 150-C251NBD is an Allen-Bradley SMC-3 series 251 A smart motor controller, open-type enclosure. It regulates motor starting and stopping by providing soft-start, kick-start, soft-stop, current limiting, inside-delta bypass, and built-in overload protection. It controls three-phase motors rated up to 132 kW (delta up to 250 kW) at 380-415 V AC systems, and manages motor control and protection functions in industrial motor applications.
Best Suited For
- 3-phase motor starting and protection
- Inside-delta bypass motor installations
- Facilities requiring adjustable soft-start and soft-stop control
- Applications with integrated overload and current-limit functions
