Allen-Bradley 150-F43NBR SMC-Flex Solid State Controller Overview

Product Introduction

When industrial motor starting demands precision and reliability, the Allen-Bradley 150-F43NBR delivers. This solid state controller from the SMC-Flex product line provides a 43 A controller rating and 30 Hp at 460V AC. It operates on a 200-460V AC, 3-phase input line at 50 and 60 Hz. The 150-F43NBR uses a 24V AC/DC control voltage, suitable for 5-480 A units. Designed for standard three-phase squirrel cage induction and 6-lead motors, it offers multiple starting modes including soft start with selectable kickstart, current limit with selectable kickstart, Dual Ramp start, Full Voltage start, Preset slow speed Linear speed Acceleration (with Tach Feedback), and Soft stop. Programming is straightforward via the built-in keypad and LCD display, or optionally through the HIM LCD human interface module.

Technical Specifications Breakdown

The 150-F43NBR features a rated voltage of 200-460V AC. Its input line voltage is 200-460V AC, 3-phase, at 50 and 60 Hz. The control voltage is 24V AC/DC for units rated 5-480 A. These specifications allow the controller to integrate seamlessly into existing electrical infrastructure. The 50/60 Hz compatibility ensures global usability. The 24V AC/DC control voltage provides flexibility for various control system designs. The 43 A rating and 30 Hp at 460V AC make it suitable for medium-duty motor applications.

Industry Applications

The 150-F43NBR excels in applications requiring controlled motor starting to reduce mechanical stress and electrical inrush. Common uses include conveyors, pumps, fans, and compressors. In a conveyor system, soft start reduces belt wear and product damage. For pumps, the controller minimizes water hammer. The multiple starting modes allow customization for specific load requirements. The Preset slow speed mode with Tach Feedback enables precise positioning for indexing applications. The 150-F43NBR's robust design supports continuous operation in demanding industrial environments.

Installation & Setup Guidance

Proper installation of the 150-F43NBR is critical for performance and longevity. Follow the typical wiring patterns specified in the manual. Mount the controller in a clean, dry location with adequate ventilation. Ensure the motor is not undersized and the controller is not oversized for the application. An isolator contactor circuit breaker is recommended on the line side to protect against faults. Verify that the input line voltage matches the 200-460V AC, 3-phase requirement. Connect the 24V AC/DC control voltage correctly. Use the built-in keypad and LCD display for initial programming. Select the appropriate starting mode for the motor and load.

Maintenance & Reliability

Regular inspection ensures long service life. Check for loose connections, signs of overheating, or environmental contamination. The 150-F43NBR includes a thermal memory that maintains overload protection data even when control power is removed. This feature enhances safety and reliability. Provide quality power and maintain recommended temperature ranges to prevent malfunctions. Avoid application errors such as undersizing the motor or oversizing the controller. The controller meets all applicable motor overload protective device requirements. Routine maintenance should include verifying proper operation of the isolator contactor circuit breaker.

Selection Guide & Purchasing Advice

Before purchasing the 150-F43NBR, verify that the controller rating (43 A) and horsepower (30 Hp at 460V AC) match your motor specifications. Confirm the input line voltage (200-460V AC, 3-phase) and control voltage (24V AC/DC) are compatible with your facility. The open enclosure type requires installation in a suitable cabinet.
