Product Overview
The Allen-Bradley 150-F361NBRB is a Bulletin 150 SMC Flex solid-state soft starter designed for low-voltage motor control. This open-style controller delivers a robust 361 A rating, supporting motors from 150 to 300 Hp at 460V AC. With an input voltage range of 200–480V AC and a 24V AC/DC control voltage, the 150-F361NBRB offers flexible integration into existing control systems.
Part of the SMC Flex family, this unit provides a solid-state power structure with a current range of 90–520 A (or 108–480 A with internal bypass). It includes 17 start and stop modes, four special operating modes, three hardware expansion ports, and built-in electronic motor overload protection. The optional communication modules support multiple networks, and programming can be done via Connected Components Workbench™ software.

- 17 start and stop modes allow precise control for various applications.
- Four special operating modes handle demanding load conditions.
- Three hardware expansion ports enable future upgrades.
- Built-in electronic motor overload protection eliminates the need for separate overload relays.
- Optional communication modules support multiple network protocols (e.g., EtherNet/IP, DeviceNet, ControlNet).
- Programming via Connected Components Workbench™ software simplifies setup and monitoring.
Applications
The 150-F361NBRB is ideal for pump control applications, where its soft-start capability reduces water hammer and mechanical stress. It also suits conveyors, fans, compressors, and other industrial machinery requiring controlled acceleration and deceleration.
In a typical pumping station, the 150-F361NBRB ensures smooth startup and shutdown, extending pump life and reducing maintenance costs. Its wide voltage range and robust design make it a reliable choice for both new installations and retrofits.
Installation & Setup
Mount the 150-F361NBRB in a clean, dry enclosure with adequate ventilation. Ensure the input line voltage matches the specified range (200–480V AC, 3-phase). Connect the control voltage (24V AC/DC) to the appropriate terminals. For fan operation, provide a separate 120V or 240V single-phase supply as noted. Use the optional Human Interface Module or PC-based software to configure start/stop modes and motor parameters.
Maintenance & Reliability
Regularly inspect the unit for dust accumulation and loose connections. Check the cooling fan (if present) for proper operation. The solid-state design minimizes wear, but periodic thermal imaging can detect potential issues. With proper care, the 150-F361NBRB delivers long service life and reduced downtime.
Compatibility & Integration
The 150-F361NBRB integrates with Allen-Bradley control systems and supports optional communication modules for network connectivity. It works with standard three-phase induction motors within the specified rating. The optional Parameter Configuration Module, Human Interface Module, or PC software allow flexible programming and monitoring.
Buying Guide
When purchasing the 150-F361NBRB, verify that your motor's full-load current does not exceed 361 A and that the input voltage matches your facility's supply. Consider the enclosure type (open) and whether you need the Pump Control option. PLC Source PRO offers this unit as a genuine Allen-Bradley spare, ensuring compatibility and reliability. Check stock availability and lead times before ordering.
