Product Overview
The Allen-Bradley 150-F480NBR is an SMC-Flex smart motor controller designed for demanding industrial applications. This solid state controller delivers 480 A to motors rated up to 400 Hp at 460V AC, making it a robust solution for soft starting and stopping large AC motors.
With an open enclosure (IP00), the 150-F480NBR is intended for installation inside a fan-vented IP54 (Type 2) electrical cabinet. It operates on a 200-460V AC, 3-phase, 50/60 Hz input line, ensuring compatibility with global power systems.
Key Features & Benefits
The 150-F480NBR offers multiple control methods to reduce mechanical stress and save energy:
- Soft start, current limit, full voltage, dual ramp, preset slow speed, kickstart, and linear speed control
- SCR bypass contactor for efficient operation
- Electronic motor overload protection
- Metering capability and DPI communication feature
- Four programmable auxiliary contacts
- Integrated HMI with LCD display and numeric keypad
These features help extend motor life, reduce downtime, and improve process control in critical applications.

Industry Applications
The Allen-Bradley 150-F480NBR is ideal for applications requiring controlled acceleration and deceleration of high-inertia loads. Typical uses include conveyors, pumps, fans, compressors, and mixers in industries such as mining, water treatment, and manufacturing.
By implementing soft start, the 150-F480NBR minimizes mechanical shock and electrical stress, reducing maintenance costs and extending equipment life. Its energy-saving capabilities also contribute to lower operational expenses.
Installation & Setup Guidance
Install the 150-F480NBR inside a fan-vented IP54 (Type 2) electrical cabinet to protect it from liquids, dust, and conductive particles. Ensure ambient temperature remains between -5°C and 50°C (23°F to 122°F).
Connect the controller to a 200-460V AC, 3-phase, 50/60 Hz supply. Wire control power to the 24V AC/DC terminals. Use the built-in HMI for programming; optional 20-HMI LCD modules are also available.
Maintenance & Reliability
Regularly inspect the cabinet filters and verify that ventilation is unobstructed. Check all power and control connections for tightness. The SCR bypass contactor reduces wear on starting components, but periodic testing of the overload protection is recommended.
Maintaining proper ambient conditions and a clean environment ensures long service life and reliable operation.
Selection Guide & Purchasing Advice
Before purchasing, verify that the 150-F480NBR meets your motor's voltage and current requirements. Confirm your control voltage needs (24V AC/DC) and ensure your cabinet can accommodate the unit's dimensions and heat dissipation.
