ALLEN BRADLEY 150-C43NBD For Parts SMC-3 Motor Controller

Product Overview

The Allen-Bradley 150-C43NBD (SMC-3) is a high-performance, compact Solid-State Smart Motor Controller designed for the smooth starting and stopping of three-phase industrial motors. As a Series B unit, it features an integrated bypass contactor that minimizes heat generation during run-time, significantly extending the life of the device. Rated for 43 Amps and 480V AC, this controller is ideal for reducing mechanical stress on belts, gears, and couplings in applications such as pumps, fans, and conveyors. As a Used Working unit, it provides a reliable, heavy-duty soft-start solution for demanding industrial environments.

Key Features

• Integrated Bypass Contactor: Automatically closes once the motor reaches full speed, reducing power dissipation and eliminating the need for external cooling in many applications.
• Selectable Start/Stop Profiles: Features four adjustable modes: Soft Start, Current Limit Start, Selectable Kickstart, and Soft Stop (0–30 seconds).
• Compact DIN Rail Design: One of the smallest footprints in its class, allowing for easy integration into high-density motor control centers (MCCs).
• Comprehensive Motor Protection: Includes built-in electronic motor overload protection, phase loss/imbalance detection, and SCR short-circuit monitoring.
• 3-Wire Configuration: Standard power wiring setup for straightforward installation in industrial 3-phase 480V systems.
• Delta Compatibility: Supports both Line and Inside-the-Delta motor connections, providing flexibility for various motor winding types.
• Easy Setup: Utilizes simple DIP switches and rotary dials for parameter configuration—no complex programming software required for basic operation.

Item Condition (Used Working)

• Functional Status: Used Working. This motor controller has been professionally bench-tested. The control logic powers up correctly, and the bypass contactor has been verified to engage upon completion of the ramp-up cycle.
• Physical State: Clean industrial condition. The power terminal lugs are in excellent shape and free of cross-threading. The front-panel configuration dials and DIP switches are fully functional.
• Technical Integrity: Tested for phase balance and insulation resistance. The cooling fans (if applicable) and heat sinks are clear of heavy industrial debris.
• Note: Professional electrical installation is required. Ensure the "NBD" control voltage (100–240V AC) is correctly applied to the control terminals to avoid logic failure.
