The Allen-Bradley 150-F5NBRD, also cataloged as the 150-F5NBRD Smart Motor Controller, operates as a dedicated hardware component for solid-state soft starting, controlled acceleration, and braking execution within 3-phase low-power induction motor circuits.

Part Number Structure & Function Identifiers

The ordering code 150-F5NBRD defines a Bulletin 150 solid-state controller from the SMC Flex series. The alphanumeric designation indicates an open enclosure physical arrangement with a rated continuous current capacity of 5 A, supporting up to 3 HP applications at 460 VAC. Functional codes specify integrated braking control and low-voltage 24 VAC/DC / 230...240 VAC control supply compatibility across a 200..480 VAC, 3-phase power line input.

Mechanical and Electrical Specifications

Deterministic Communications & Network Integration

The controller interfaces with programmable automation systems through optional communication gateways transmitting parameters over EtherNet/IP deterministic networks. High-efficiency backplane bus communication velocity and strict firmware flash compatibility allow real-time diagnostic reporting, seamless I/O density scaling, and precise stopping synchronization inside motor control centers.

Wiring and Panel Mounting Guidelines

• Enclosure Orientation: Mount the open frame structure vertically inside an outer cabinet to ensure unobstructed convection cooling across the internal heat sink assemblies.
• Control Supply Connections: Route dedicated control power wires (24 VAC/DC or 230...240 VAC) using twisted, shielded conductors separated from main AC power cables.
• Power Line and Load Wiring: Connect the 3-phase line power (200..480 VAC) and motor leads securely to main terminals, torqueing to factory specifications to prevent terminal overheating under 5 A continuous load.
• System Earthing: Secure a low-impedance ground conductor directly between the chassis ground stud and the enclosure main ground busbar.

Frequently Asked Questions

• What is the continuous operational current rating of the 150-F5NBRD?

  The solid-state motor controller manages continuous line currents up to 5 A in 3-phase motor power circuits.

• What main input voltage range can be applied to the power terminals?

  The power switching stage supports a 3-phase line input range of 200..480 VAC at 50/60 Hz.

• What control supply voltage options are supported by this module?

  The control circuit accepts nominal control input voltages of 24 VAC/DC or 230...240 VAC single-phase power.

• What maximum motor power output does this unit support at 460 VAC?

  The starter controls 3-phase AC induction motors rated up to 3 HP when operated on a 460 VAC supply line.

• Does this starter model support controlled deceleration features?

  Yes, catalog revision 150-F5NBRD includes integrated braking control logic for rapid motor stopping execution.

• Is the 150-F5NBRD built inside a protective weatherproof housing?
