Product Overview
The Allen-Bradley 150-F201NCR is a solid-state smart motor controller from the SMC-Flex product line. It is designed for industrial automation applications requiring reliable motor starting and protection. This open-type controller supports a three-phase input line voltage of 200-575V AC at 50 and 60 Hz, making it versatile for global installations.
With a controller rating of 201 A and 150 HP at 460V AC, the 150-F201NCR handles demanding loads. The rated voltage is 500/575V AC, and it uses a 24V AC/DC control voltage (for 5-480 A units). This model is compatible with standard squirrel-cage induction motors and Wye-delta, six-lead motors.

The 150-F201NCR provides a motor current range of 116 to 348 A, with maximum ratings of 250 kW at 50 Hz and 300 HP at 60 Hz. These figures ensure compatibility with a wide range of industrial motors.
Key Features and Applications
This controller offers multiple start and stop modes, including current limit start, preset slow speed, dual ramp, soft stop, linear speed acceleration, full voltage, and soft start. These options allow precise control over motor acceleration and deceleration, reducing mechanical stress and extending equipment life.
Typical applications include conveyors, pumps, fans, compressors, and other heavy machinery where smooth starting and stopping are critical. The 150-F201NCR is also suitable for processes that require adjustable speed control or frequent starts and stops.
Installation and Setup
When installing the Allen-Bradley 150-F201NCR, ensure the enclosure is mounted in a clean, dry location with adequate ventilation. The controller should be installed at an altitude not exceeding 2000 meters. Verify that the input line voltage matches the supply and that the control voltage is correctly wired.
Connect the motor according to the wiring diagram provided in the manual. For Wye-delta motors, ensure the six-lead configuration is properly connected. After installation, test the controller with the motor disconnected to verify correct operation of the control circuit.
Maintenance and Reliability
The 150-F201NCR is designed for long-term reliability. Routine maintenance should include checking for loose connections, inspecting the enclosure for dust or moisture, and verifying that the cooling vents are unobstructed. The controller’s ambient temperature range for operation is 23 to 104 °F (-5 to 50 °C), and for storage it is -4 to 167 °F (-20 to 75 °C).
Periodically test the fault detection features to ensure they are functioning correctly. The controller can detect phase reversal, overvoltage, undervoltage, jam, underload, stall, overload, voltage unbalance, communication faults, controller temperature, and line faults. Early detection of these issues helps prevent unexpected downtime.
Selection Guide and Purchasing Advice
Before purchasing, confirm that the 150-F201NCR meets your motor’s full-load current and voltage requirements. Verify the enclosure type—this is an open-type unit, so it is not suitable for harsh or dusty environments without additional protection. Ensure that the control voltage (24V AC/DC) is available in your control panel.
