Allen-Bradley 150-F85NBDD SMC-Flex Soft Starter: 85A, 460V, 60HP

Why Choose the Allen-Bradley 150-F85NBDD SMC-Flex Soft Starter?

nnWhen your facility faces motor starting challenges like excessive inrush current or mechanical stress, the Allen-Bradley 150-F85NBDD SMC-Flex soft starter provides a reliable solution. This solid-state, low-voltage controller from the SMC-Flex family delivers microprocessor-controlled starting for standard three-phase industrial induction motors. With ratings of 460 Volts AC (3-phase), 85 Amps, and 60 Horsepower, it ensures smooth acceleration and deceleration while protecting your equipment.nn

Technical Specifications Breakdown

nnThe 150-F85NBDD operates on a line input voltage of 460 Volts AC and a control voltage of 200 to 230 Volts AC. Its current rating of 85 Amps supports motors up to 60 Horsepower. The built-in 3-line by 16-character LCD display and 5-button front panel keypad simplify parameter programming and diagnostics. Four fully programmable auxiliary contacts (N.O. and N.C.) allow flexible integration with network, alarm, up-to-speed, normal, or fault control schemes. The controller also includes built-in DPI communication capability for connecting HMI modules and communication modules.nn

Industry Applications

nnThis soft starter excels in applications requiring controlled starting and stopping of induction motors. In conveyor systems, it reduces mechanical shock and extends belt life. For pumps, it minimizes water hammer and pressure surges. In HVAC systems, the 150-F85NBDD provides smooth ramp-up for fans and compressors, lowering electrical stress on the grid. The optional smart motor braking control enables faster stopping than coast-to-rest, ideal for material handling and processing equipment.nn

Installation & Setup Guidance

nnMount the 150-F85NBDD in a clean, dry enclosure with adequate ventilation. Ensure the line input voltage matches 460 Volts AC and the control voltage is within 200 to 230 Volts AC. Wire the three-phase motor to the output terminals and connect auxiliary contacts as needed. Use the 5-button keypad and LCD screen to configure starting modes, protection parameters, and communication settings. Always follow local electrical codes and the manufacturer’s manual for safe installation.nn

Maintenance & Reliability

nnThe SMC-Flex design includes built-in SCR bypass for efficient operation after starting. Protective features like underload, jam, stall, over-voltage, under-voltage, voltage unbalance, and electronic motor overload protection reduce unplanned downtime. Inspect the controller periodically for dust accumulation on the heatsink and verify all connections are tight. The LCD display aids quick diagnostics, allowing operators to monitor status and fault history. Regular inspection and testing according to the manufacturer’s guidelines ensure long service life.nn

Compatible Systems & Integration

nnThe 150-F85NBDD integrates seamlessly with Allen-Bradley control systems via its built-in DPI communication interface. This serial interface supports connection to HMI modules and a wide range of communication modules, enabling remote monitoring and control. The four programmable auxiliary contacts can be wired to PLCs or other automation devices for status feedback. For applications requiring faster stopping, the optional smart motor braking control enhances system performance.nn

Selection Guide & Purchasing Advice

nnBefore purchasing the 150-F85NBDD, verify that your motor’s full-load current does not exceed 85 Amps and the supply voltage matches 460 Volts AC. Confirm the control voltage source is 200 to 230 Volts AC. Consider the optional braking control if your process demands rapid stopping.
