The 150-F251FHD is one of the Bulletin 150 Flex Smart Motor Controllers manufactured by Allen Bradley. It provides a 251 A current and generates 200 Hp at 460 Volts AC. This module is rated for an IP65 enclosure and this unit requires a 3-phase input power of 200 to 208 Volts AC at 50 to 60 Hertz. It has a control voltage of 100 to 240 Volts AC. The 150-F251FHD, just like the other controllers from the Bulletin 150 line, has built-in features that are unavailable in other soft starter controllers on the market. It has a compact size that makes it easy to install in any application. The Allen Bradley controller also has modular communication capabilities and motor starting capabilities for standard squirrel-cage and star-delta induction motors.

By using the 150-F251FHD, companies reduce the mechanical damage that occurs due to full-voltage starting of induction motors. As a result, this module makes the system last longer. This controller also reduces downtime by limiting the number of line disturbances due to inrush currents. It has several start/stop modes that offer more functionality and has built-in diagnostic tools that help prevent a large variety of issues. This controller complies with electrical distribution restrictions by lowering inrush currents. The 150-F251FHD is ideal for applications in which materials can be damaged by sudden stops and starts, areas with power company line current restrictions, solid-state starting for a Star-Delta motor application, areas that have limited space for the enclosure, step change in torque damaging equipment, gears, chains, and belts damaged by a line starting. The 150-F251FHD has a modular design that’s perfect for commissioning and installation. The modular design also allows ease of maintenance. Operators can easily replace components due to the controller’s modular power structure.
