Information About 150-A35NB-ND

The 150-A35NB-ND is part of the Allen-Bradley SMC-2 Smart Motor Controller family, designed for consistent and reliable soft-start performance in industrial systems. Its open-type construction simplifies integration into control panels and supports a full 35 A operational load. With support for multiple voltage classes, including 200/230 VAC, 460 VAC, and 575 VAC, the controller adapts to a wide variety of motor applications. Functions such as controlled acceleration, current limiting, soft stop, and across-the-line starting ensure stable operation across demanding industrial environments.

Key Features

  • Soft Start Function: gradually increases voltage to reduce inrush current and prevent mechanical stress.
  • Current Limit Mode: maintains a preset current threshold to protect electrical components during start-up.
  • Soft Stop Control: provides smooth motor deceleration suitable for pumps, conveyors, and sensitive loads.
  • Multi-Voltage Motor Support: handles 10 HP at 200/230V, 25 HP at 460V, and 30 HP at 575V applications.
  • Global Frequency Compatibility: supports operation at both 50 Hz and 60 Hz.
  • Versatile kW Ratings: supports 10 kW (200V), 18.5 kW (380V), and 22 kW (415/500V).
  • Integrated Protection Modes: includes soft start, across-the-line start, current limiting, and shutdown functions.
  • Auxiliary Control Interface: features a 100–120V AC input for external control integration.

The 150-A35NB-ND delivers the reliability and precision required for controlled motor acceleration, deceleration, and industrial equipment protection.

Frequently Asked Questions about 150-A35NB-ND
Question: What is the 150-A35NB-ND?
Date Update:18/06/2025
Answer:

The 150-A35NB-ND is an SMC-3 solid-state soft starter from Allen-Bradley, rated for up to 35 A, 3-phase motors, and operates at up to 480V AC. It’s used to soft-start and soft-stop AC induction motors, reducing mechanical wear and electrical stress by ramping voltage during startup.

Question: What are the key specifications of the 150-A35NB-ND?
Date Update:18/06/2025
Answer:
  • Rated Current: 35 A
  • Voltage Class: 200–480V AC
  • Control Voltage: 100–240V AC
  • Motor Type: 3-phase squirrel cage
  • Start Modes: Soft Start, Current Limit Start
  • Stop Modes: Soft Stop or Coast to Stop
  • Built-in Protections: Overload, phase loss, undervoltage

It is suitable for applications like pumps, conveyors, and fans.

Question: How is the 150-A35NB-ND wired?
Date Update:18/06/2025
Answer:
  • Line inputs (L1, L2, L3) connect to the incoming 3-phase AC supply.
  • Motor outputs (T1, T2, T3) connect to the motor leads.
  • Control terminals provide start/stop, reset, and auxiliary relay output functions.
  • Wiring must follow NEC standards and Rockwell’s wiring diagrams. Always use proper fusing and grounding.
Question: Does the 150-A35NB-ND support programming or configuration?
Date Update:18/06/2025
Answer:

Yes. Configuration is done via DIP switches and rotary dials on the front panel. You can:

  • Select start mode (soft start or current limit)
  • Adjust start/stop time (0–30 seconds)
  • Set motor overload trip class

It does not support digital networking, but higher-end SMC models do.

Question: What are the 150-A35NB-ND common troubleshooting issues?
Date Update:18/06/2025
Answer:
  • No start: Check control voltage, start signal, and overload status.
  • Overload trips: Verify FLA setting and cooling conditions.
  • Phase loss fault: Ensure stable 3-phase input supply.
  • Motor chattering: May result from incorrect start mode or ramp time settings.

The unit has status LEDs that indicate fault, run, or ready states.
