Schneider ATS22C25S6U Altistart 22 Soft Starter

Description

The ATS22C25S6U is an Altistart 22 soft starter from Schneider Electric, engineered for the controlled starting and stopping of 3-phase asynchronous motors. This unit is designed to effectively manage inrush currents, thereby reducing mechanical torque shocks and electrical stresses on the motor and coupled load during start-up.

Supporting a wide voltage range of 208 V to 600 V, the ATS22C25S6U is suitable for a broad spectrum of industrial motor applications, handling power ratings between 75 HP and 250 HP with a rated operational current of 250 A. Its compact design facilitates efficient space utilization within control panels, while the integrated bypass contactor improves energy efficiency and reduces heat generation during steady-state operation.

Installation Guidelines

• Mounting: The unit must be installed vertically in a control cabinet with adequate ventilation. Maintain the recommended clearance distances to ensure sufficient airflow for heat dissipation.
• Environment: Ensure the installation environment is free from corrosive gases, excessive moisture, and conductive dust to prevent internal component damage.
• Wiring: Connect the power input and motor leads according to the system's power capacity. Ensure all power terminals are tightened to the specified torque settings.
• Grounding: A secure protective earth (PE) connection to the chassis is required to satisfy safety standards and EMC guidelines.
• Configuration: Utilize the integrated configuration settings to adjust starting torque and ramp times to match the specific load characteristics of the motor application.
