Configured for controlled solid-state starting, braking execution, and current limiting in 3-phase motor power circuits, the Allen-Bradley 150-F25NBDD (150-F25NBDD Smart Motor Controller) provides direct physical/electrical execution.

Ordering Code & Nomenclature Configuration

The catalog identifier 150-F25NBDD designates a solid-state soft starter from the Bulletin 150 SMC Flex product family. The internal hardware assembly features an open enclosure physical frame rated for a continuous operating current of 25 A (5-15 HP output at 460 VAC), an operating 3-phase line input range of 200-460 VAC at 50/60 Hz, integrated braking control capability, and a nominal 100...240 VAC control circuit interface.

Technical Performance Parameters

Deterministic Network Interfacing & Expansion

The controller integrates into modern control architectures via optional communication modules operating across EtherNet/IP deterministic networks, delivering real-time operational status updates to host controllers. Firmware flash compatibility protects against software mismatches during device replacement, while predictable cycle timing supports consistent I/O density scaling and coordinated deceleration profiles inside motor control cabinets.

Delivery Package Components

• 1 x Allen-Bradley 150-F25NBDD SMC Flex Smart Motor Controller
• 1 x Protective Static-Shield Packaging Unit
• 1 x Initial Field Wiring and Installation Leaflet

Physical Mounting & Field Connection Rules

• Enclosure Clearance: Secure the open frame module vertically inside a protective outer cabinet, preserving unobstructed vertical airflow paths over the integrated heatsink assembly.
• Control Power Wiring: Connect the single-phase 100...240 VAC control supply lines to specified control terminals using isolated, noise-shielded conductors.
• Line and Load Connections: Torque 3-phase line (200-460 VAC) and motor load terminations to standard factory specification limits to prevent resistive heating under 25 A full-load operation.
• Grounding Requirements: Install a dedicated copper grounding conductor between the chassis earth ground terminal and the panel central earth grounding bus.

Technical FAQs

• What is the continuous output current rating for the 150-F25NBDD?

  The solid-state motor controller manages continuous operational currents up to 25 A across 3-phase power circuits.

• What line supply voltage range is supported on the power terminals?

  The main power switching stage accepts a 3-phase line input voltage ranging from 200 VAC to 460 VAC at 50/60 Hz.

• What control input voltage is required for internal logic execution?

  The control circuit terminals require a single-phase AC control supply voltage ranging from 100 VAC to 240 VAC.

• Does this starter model include dynamic deceleration features?

  Yes, catalog model 150-F480NBRD includes integrated braking control circuitry designed for active motor stopping functions.

• What maximum motor horsepower can be driven at 460 VAC?

  The soft starter controls 3-phase AC induction motors rated up to 15 HP (5-15 HP range) at 460 VAC line input.

• Is the 150-F25NBDD provided with an integrated weatherproof housing?
