Allen-Bradley 150-F85NBR SMC Flex Smart Motor Controller

Product Overview

The Allen-Bradley 150-F85NBR is a Smart Motor Controller from the SMC Flex product family, commonly known as a motor soft-starter. This solid-state device is engineered to reduce mechanical stress and electrical inrush during motor starting and stopping, lowering power consumption and operational costs.

Technical Specifications Breakdown

Key parameters for the 150-F85NBR are listed below for quick reference:

Industry Applications

This motor controller is well-suited for pumping systems, conveyor lines, and HVAC equipment where smooth acceleration reduces mechanical wear and fluid hammer. For pump control, the soft start and soft stop modes minimize pressure surges, extending pipeline and valve life. In material handling, the current limit and dual ramp start features allow precise torque management during startup, protecting belts and gearboxes.

Installation & Setup Guidance

Mount the controller on a panel using the provided mounting points. Ensure the input line voltage matches the 200-460V AC, 3-phase supply and that the control voltage is 24V AC/DC. Connect the motor as per the wiring diagram for line-connected or Delta-connected configurations. Use the built-in keypad with LCD to configure start modes such as Soft Start, Kickstart, or Current Limit. Adjust start time from 2 to 30 seconds and kickstart duration from 0 to 1.5 seconds at 450% FLA as needed.

Maintenance & Reliability

Periodically inspect the open-style enclosure for dust accumulation and ensure adequate ventilation. Verify that the controller temperature remains within safe operating limits. The built-in protection features—including overload, underload, voltage unbalance, and ground fault detection—help prevent unexpected downtime. Check the status indicators (stopped, starting, at speed, alarm, fault) regularly to monitor system health.

Compatibility & Integration

The 150-F85NBR integrates with standard squirrel-cage induction motors or Wye-Delta, six-lead motors. It includes one DPI port for an optional HMI and another DPI port for an expansion module. The four fully-programmable auxiliary contacts and alarm contacts (overload, underload, undervoltage, overvoltage, unbalance, jam, stall, ground fault) allow flexible integration with PLCs and SCADA systems.

Selection Guide & Purchasing Advice

When selecting a motor controller, verify that the motor type (squirrel-cage or Wye-Delta) and voltage (200-460V AC) match the 150-F85NBR specifications. For applications requiring precise metering of amps, volts, kW, kWh, power factor, and motor thermal capacity, this controller provides built-in capabilities.
