Schneider Altistart 22 ATS22C11S6U Soft Starters

Description

The ATS22C11S6U is a high-performance soft starter from the Altistart 22 range, designed to provide controlled acceleration and deceleration for three-phase asynchronous motors. Engineered to handle a rated current of 110 A across a wide input voltage range of 208-600 V, this unit supports motor power ratings between 30 HP and 100 HP. By regulating voltage and torque during the start-up phase, the ATS22C11S6U effectively minimizes mechanical stress on couplings and belts while reducing peak current demand on the power grid. It is a robust solution for enhancing the operational life of motor-driven equipment in heavy-duty industrial environments.

Features

• Optimized for 110 A rated asynchronous motor current.
• Wide voltage compatibility: 208 V to 600 V.
• Supports a motor power range of 30 HP to 100 HP.
• Integrated bypass contactor for reduced heat dissipation and improved efficiency.
• Advanced protection features for motor and starter thermal management.

Applications

• Centrifugal pumps and fluid management systems.
• Industrial fans, blowers, and air handling units.
• Conveyor belts and material handling machinery.
• Compressors and agitators requiring smooth torque transitions.

Installation Guidelines

• Mounting: The ATS22C11S6U should be mounted vertically to allow for optimal airflow through the internal heatsink.
• Clearance: Ensure at least 100 mm of space above and below the unit to prevent thermal derating.
• Wiring: Tighten power terminal connections to the manufacturer-specified torque to avoid overheating at high current loads.
• Environment: Install in a location protected from moisture and conductive dust; for harsh environments, a NEMA/IP-rated enclosure is required.
• Grounding: A secure chassis ground connection is essential to maintain electromagnetic compatibility and personnel safety.
