Configured for controlled solid-state starting, braking execution, and current limiting in 3-phase high-power induction motor circuits, the Allen-Bradley 150-F970NBAD (150-F970NBAD Smart Motor Controller) provides direct physical/electrical execution.

Model Structure & Rating Identification

The designation 150-F970NBAD represents a Bulletin 150 solid-state controller architecture within the SMC Flex framework. The alphanumeric structure denotes an open enclosure physical frame rated for a maximum continuous output of 970 A, supporting up to 800 HP applications at 460 VAC, operating across 200..480 VAC line power, and requiring a nominal 230...240 VAC control source.

Electrical and Physical Parameters

Deterministic Communications & Network Integration

Data transmission to central controllers uses optional interface gateways operating across EtherNet/IP deterministic networks to deliver sub-millisecond diagnostic reporting. Backplane bus communication velocity and firmware flash compatibility allow system parameter updates, maintaining seamless I/O density scaling and coordinated stopping cycles across multi-starter panels.

Panel Mounting & Power Wiring Guidelines

• Enclosure Clearance Requirements: Install the open-type unit upright within a dust-free enclosure, ensuring clear vertical airflow paths over the thyristor heatsinks.
• Line and Load Connections: Secure power cables or busbars to 3-phase input (200..480 VAC) and motor load terminals using correct bolt torque specifications to avoid thermal stress.
• Control Power Wiring: Connect dedicated 230...240 VAC control supply lines to the control terminals via isolated, noise-shielded conductors.
• System Grounding Standards: Run high-integrity, low-impedance grounding straps from the metal chassis ground terminal directly to the panel main earth busbar.
