Schneider Electric Altistart 22 ATS22D75S6U Soft Starter

Description

The ATS22D75S6U is a Schneider Altistart 22 Soft Starter engineered for the controlled starting and stopping of three-phase asynchronous motors. Designed to reduce mechanical stress and electrical surges during motor startup, this soft starter manages a nominal current of 75 A and operates across a wide voltage range of 208V to 600V. It provides power control for motors rated between 20 HP and 60 HP, depending on the application voltage. The ATS22D75S6U features integrated bypass contactors and comprehensive protection functions to safeguard motors and machinery from overload, phase failure, and phase imbalance.

Installation Guidelines

• Mounting: Install the soft starter in a vertical orientation within an enclosure that provides adequate ventilation. Ensure sufficient clearance is maintained above and below the unit to allow for convective cooling.
• Environmental: Ensure the installation environment is free from dust, moisture, and corrosive gases. Use an enclosure with the appropriate IP rating for the specific application environment.
• Wiring: Connect the line supply (L1, L2, L3) and motor terminals (T1, T2, T3) using appropriately sized power conductors as specified in the local electrical code.
• Grounding: Secure a solid connection to the cabinet's main protective earth (PE) bus to ensure electrical safety and effective noise mitigation.
• Configuration: Utilize the integrated keypad or communication interface to set starting parameters (torque ramp and voltage limit) tailored to the specific load characteristics of the motor.
