Motor Soft-Start & Protection Solution – Allen-Bradley 150-F60NBRB | SMC-Flex Series
The Allen-Bradley 150-F60NBRB is a full-featured Smart Motor Controller from Rockwell Automation’s SMC-Flex platform, engineered for 60-ampere motor loads operating on 200–480V AC three-phase systems. Designed for procurement engineers who demand reliable, spec-accurate components, this unit delivers controlled soft-start and soft-stop functionality that extends motor and mechanical drivetrain life in demanding industrial environments.
Where This Product Is Used
The 150-F60NBRB is specified across a broad range of motor-driven applications where across-the-line starting causes mechanical stress, voltage sag, or excessive inrush current:
- Conveyor & Material Handling Systems — Eliminates belt jerk and product spillage on startup; reduces gearbox wear on long conveyor lines in warehouses, ports, and mining operations.
- Pump Stations & Water Treatment — Prevents water hammer in pipeline systems; widely used in municipal water/wastewater plants, irrigation pump stations, and HVAC chilled-water loops.
- HVAC Fan & Blower Applications — Reduces mechanical stress on fan blades and ductwork during startup; common in air-handling units, cooling towers, and industrial ventilation systems.
- Compressor Drives — Controls inrush current on reciprocating and screw compressors in oil & gas, refrigeration, and pneumatic systems.
- Mixer & Agitator Drives — Provides smooth torque ramp-up for chemical processing, food & beverage mixing, and wastewater aeration equipment.
- Crusher & Mill Drives — Manages high-inertia loads in aggregate, cement, and mining applications where full-voltage starting is impractical.

Why Engineers Specify This Model
- Internal Bypass Contactor — The “B” suffix denotes a built-in bypass contactor, eliminating the need for an external bypass panel and reducing panel footprint by up to 30%.
- SMC-Flex Intelligence — Onboard diagnostics, event logging, and parameter storage via DPI port allow rapid commissioning and predictive maintenance integration.
- Flexible Starting Profiles — Independently adjustable initial torque, ramp time (1–30 s), and current limit (50–600% FLA) accommodate diverse load characteristics without external components.
- Integrated Motor Protection — Replaces separate overload relay, phase-loss relay, and jam relay — reducing BOM count and wiring complexity.
- Network-Ready Architecture — Optional DeviceNet module enables full integration into Allen-Bradley ControlLogix / CompactLogix PLC architectures with RSLogix 5000 / Studio 5000 programming.
- Proven Reliability — SMC-Flex is a globally installed platform with millions of operating hours across process, discrete, and infrastructure industries.

Application-Specific FAQ
Q: Can the 150-F60NBRB be used with a VFD on the same motor?
A: No. SMC-Flex controllers are designed for across-the-line motor applications. Using a soft starter and VFD on the same motor simultaneously is not supported and will damage both devices. Choose one technology based on your speed-control requirements.
Q: What is the difference between 150-F60NBRB and 150-F60NBR?
A: The trailing “B” in 150-F60NBRB denotes the inclusion of an internal bypass contactor. The 150-F60NBR (without trailing B) requires an external bypass contactor to be wired separately. The NBRB variant simplifies panel design and reduces installation cost.
Q: Is DeviceNet communication included as standard?
A: No. The base 150-F60NBRB includes a DPI port for local parameter access and HMI connection. DeviceNet communication requires the optional 20-COMM-D adapter module, ordered separately.
Q: What motor protection is built in without additional modules?
A: Standard protection includes electronic overload (Class 10/15/20/30 selectable), phase loss, phase imbalance, stall, jam, underload, and open-circuit fault detection. Ground fault protection requires an optional external CT module.
Q: Can this unit be programmed via Studio 5000 / RSLogix 5000?
A: Yes, when equipped with the DeviceNet or EtherNet/IP communication module, the 150-F60NBRB can be fully configured and monitored from a ControlLogix or CompactLogix PLC using the appropriate Add-On Profile (AOP) in Studio 5000.
