Product Overview
The Allen-Bradley 150-F135NBRB is a Smart Motor Controller engineered for demanding three-phase motor applications. This industrial automation module delivers reliable starting and stopping control for motors rated up to 135 A, supporting 25 to 100 Hp at 460V AC. Designed for open panel mounting, it operates on 480V AC at 50/60 Hz with a 24V AC/DC control supply. Its dedicated pump control functionality makes it an ideal choice for pumping systems that require smooth acceleration and deceleration to prevent water hammer and mechanical stress.
When motor failures cause costly downtime, the 150-F135NBRB provides a robust solution. Built for continuous industrial duty, this Allen-Bradley module ensures consistent performance in harsh environments.

Industry Applications
The 150-F135NBRB excels in pumping applications across water treatment, irrigation, and HVAC systems. For example, in a municipal water booster station, the controller's pump control logic gradually ramps the motor to full speed, minimizing pressure surges and extending pump life.
In industrial processing plants, this motor controller supports conveyors and mixers that require reliable starting torque. The 135 A capacity handles medium- to large-horsepower motors, making it a versatile addition to any control panel.
Installation & Setup Guidance
Mount the 150-F135NBRB in a clean, ventilated open panel, ensuring adequate clearance for heat dissipation. Verify that the incoming 480V AC three-phase supply matches the controller's rating, and that the control circuit is wired to a 24V AC/DC source. Follow the manufacturer's wiring diagram for the pump control connections. After installation, perform a functional test with the motor disconnected to confirm the control logic operates correctly.
Maintenance & Reliability
Regularly inspect the controller's power terminals for signs of overheating or loose connections. In dusty environments, clean the enclosure and heatsink periodically to maintain thermal performance. Because the unit is open-style, protect it from direct moisture and conductive contaminants. Routine checks every six months can prevent unexpected failures and extend service life.
Selection Guide & Purchasing Advice
Before purchasing, confirm that the motor's full-load current does not exceed 135 A and that the horsepower rating falls within the 25–100 Hp range at 460V AC. Verify the supply voltage (480V AC) and frequency (50/60 Hz) match your facility. Ensure the control voltage (24V AC/DC) is available in your panel.
