150-C317FHD

The 150-C317FHD model from Allen Bradley is recognized as a solid-state motor controller configured to manage various motor operations. It operates efficiently within a voltage range of 200 to 208 Volts AC while regulating a nominal current of 317 Amperes. This motor controller is built for three-phase power systems, providing robust support for several operational modes, including Soft Start, Current Limit Start, Selectable Kickstart, Coast-to-Rest, and Soft Stop modes.

Cooling is achieved through an integrated fan system that facilitates steady-state heat dissipation, quantified at 174 Watts. The control circuit relies on an electromagnetic relay, which enhances responsive operation. Furthermore, users can adjust the starting time based on specific operational requirements, with options of 2, 5, 10, 15, 20, 25, or 30 seconds.

The device has an impressive overload current capability, covering a range from 106 to 317 Amperes, ensuring adaptability across different load conditions. With a shock resistance rating of 15 G in operating mode and up to 30 G when not operational, this controller is designed to withstand dynamic conditions. Additionally, it operates effectively within a frequency range of 50 to 60 Hertz. The dielectric withstand voltage reaches 2,200 Volts AC, qualifying it under applicable safety standards such as UL, CSA, and NEMA.
