Schneider Electric Soft Starters
Schneider Electric Soft Starters – Product Overview
Schneider Electric’s Altistart Soft Starter series is designed to provide smooth, controlled motor acceleration and deceleration, protecting mechanical systems and reducing electrical stress during start-up. By regulating inrush current and minimizing torque shock, Altistart soft starters help extend motor lifespan, reduce downtime, and improve overall system reliability. They are widely used in industries such as manufacturing, water & wastewater, HVAC, mining, and material handling.
Product Series
| Series | Power Range | Application Focus | Key Features |
|---|---|---|---|
| Altistart 22 (ATS22) | 4 to 400 kW | General industrial applications | Compact design, built-in bypass contactor, simple commissioning |
| Altistart 48 (ATS48) | 4 to 900 kW+ | Heavy-duty / high-inertia loads | Advanced torque control, thermal protection, robust performance |
| Altistart 01 (ATS01) | 0.37 to 11 kW | Small machines / pumps / fans | Basic soft start control, cost-effective, simple wiring |
Key Advantages
1. Reduced Mechanical Stress
Soft starters minimize sudden torque impact during start-up and shutdown, protecting pumps, gearboxes, belts, couplings, and other mechanical components from premature wear.
2. Lower Electrical Inrush Current
Controlled acceleration lowers current peaks typical in direct-on-line starting, reducing strain on cables, switchgear, transformers, and the overall power network.
3. Smart Motor Protection
Built-in thermal and overload protection safeguards the motor from overheating and electrical faults, improving equipment reliability and extending lifetime.
4. Smooth Process Control
Adjustable ramp-up and ramp-down settings allow optimized motor operation, reducing pressure surges in pumps (water hammer) and preventing material spilling in conveyors.
5. Easy Installation and Setup
Compact dimensions, integrated bypass contactors (ATS22), and simple menu-based configuration make commissioning fast and maintenance straightforward.
6. Versatile Integration
Altistart series supports standard industrial control systems and communication protocols, making it easy to integrate with existing automation environments.
