Schneider Altistart 22 ATS22C14S6U Soft Starter

Description

The ATS22C14S6U is an Altistart 22 soft starter designed for the controlled starting and stopping of three-phase asynchronous motors. This unit provides current-limiting and voltage-ramping capabilities to reduce mechanical stress on drive trains and minimize inrush current during startup. It is engineered for industrial applications requiring smooth motor acceleration and deceleration to protect equipment and optimize power distribution.

Features

• Rated for 140 A operation
• Supports voltage range from 208V to 600V
• Motor power range: 40 to 125 HP
• Integrated bypass contactor for reduced heat dissipation
• Compact physical footprint for space-constrained enclosures
• Diagnostic and testing capabilities for maintenance efficiency

Applications

• Centrifugal pumps
• Fan and blower systems
• Compressors
• Conveyor belts
• General machinery requiring soft-start torque control

Installation Guidelines

• Mounting: Ensure the unit is mounted vertically on a flat, rigid surface to allow for proper airflow.
• Cooling: Maintain recommended clearance distances around the unit to prevent thermal overload. Refer to the manual for specific ambient temperature derating requirements.
• Wiring: Use appropriately sized power cables based on the 140 A rating. Ensure all terminals are tightened to the specified torque values to prevent resistive heating.
• Grounding: Proper equipment grounding is required for safe operation and electromagnetic compatibility.
• Environment: Protect the device from moisture, excessive dust, and corrosive gases to maintain operational longevity.
