The Allen-Bradley 150-F43NBR is a sophisticated solid-state controller from the SMC-Flex line, designed specifically for managing three-phase squirrel cage induction motors. With a 43A controller rating and capable of handling up to 30 Hp at 460 Volts AC, this unit operates on a 24 Volt AC/DC control voltage and supports input voltages ranging from 200 to 460 Volts AC, accommodating three-phase systems at 50 to 60 Hertz. It features a versatile range of starting modes, such as soft start, dual ramp, and full voltage start, among others, providing flexibility and precision in motor handling. Programmable via its built-in keypad and LCD display or an optional HIM LCD module, the 150-F43NBR is engineered to comply with motor overload protective device standards, including thermal memory retention to enhance safety and longevity, even in the absence of control power.
