At DDPARTSSOLUTION, we specialize in delivering advanced industrial automation components, and the Allen-Bradley SMC-3 Smart Motor Controller stands out as a reliable, space-saving, and energy-efficient solution for motor control. Also known as the ab smc 3 or soft starter smc 3, this controller is engineered to reduce mechanical stress, improve system protection, and optimize startup performance for motors ranging from 3 to 480 A.

Product Overview

The SMC-3 Smart Motor Controller from Allen-Bradley is designed for three-phase induction motors and supports applications requiring current ranges between 3 and 480 A. It accommodates supply voltages from 200 to 690V AC, making it suitable for global installations across a wide range of industries.

Its solid-state design with true three-phase control ensures consistent torque and balanced starting, while the integral bypass contactor reduces internal heat dissipation and enhances overall efficiency.

Key Features and Benefits

1. Integrated Bypass with SCR Technology

The ab smc 3 includes a silicon-controlled rectifier (SCR) bypass contactor, which reduces the thermal footprint inside control panels, minimizes power loss during operation, and increases system lifespan.

2. Multiple Start and Stop Modes

Operators can choose from five control methods:

• Soft Start

• Current Limit Start

• Kickstart

• Soft Stop

• Coast-to-Stop
  This flexibility allows fine-tuning for various motor loads and applications.

3. Electronic Overload Protection

Built-in Class 10 and Class 20 overload settings protect motors against overheating, tripping in overcurrent conditions before damage occurs.

4. Compact Footprint

Its small form factor allows for installation in tight spaces, making the soft starter smc 3 ideal for MCC (Motor Control Center) layouts and decentralized control systems.

5. Diagnostics and Ease of Use

Includes motor status diagnostics and setup via DIP switches. Features a push-to-reset and hold-to-test button, reducing commissioning and maintenance time.

Applications

The soft starter smc 3 is ideal for motor-driven applications where mechanical stress must be minimized during startup or shutdown. Common industries and use cases include:

• HVAC: Chillers and compressors

• Water/Wastewater: Pumps and blowers

• Material Handling: Conveyors and lifts

• Aggregates: Crushers and feeders

• Food & Beverage: Process mixers

Standards and Certifications

The ab smc 3 meets a wide range of global certifications, ensuring compliance and safety in international applications:

• UL Listed (Open Type)

• CSA Certified

• CE Marked (Open Type)

• CCC Certified

• RoHS Compliant

• Suitable for IE3 High-Efficiency Motors in accordance with IEC 60034-30
