Schneider Altistart 22 ATS22D88S6 Soft Starter

Description

The ATS22D88S6 is a Soft Starter from the Altistart 22 series, designed for the controlled acceleration and deceleration of three-phase asynchronous motors. By managing the voltage and torque during the start sequence, this device prevents mechanical shocks and reduces electrical inrush currents, thereby extending the lifespan of motors, belts, and gearboxes. The unit is rated for an operational current of 88 A and supports a wide supply voltage range of 230V to 600V, accommodating motor power ratings from 22 kW to 55 kW. It features an integrated bypass contactor, which minimizes heat dissipation during steady-state operation, making it an efficient solution for industrial motor control.

Features

• Integrated bypass contactor for thermal efficiency
• Soft start and soft stop control to reduce mechanical stress
• Wide voltage range (230-600V) for global application flexibility
• Compact physical design for high-density cabinet installation
• Simplified configuration through display and keypad interface

Applications

• Centrifugal pumps and fan systems
• Conveyors and material handling equipment
• Compressors
• Mixers and agitators
• General industrial machinery requiring controlled starts

Installation Guidelines

• Mounting: Install in a vertical position with adequate clearance above and below the unit to facilitate airflow through the cooling vents.
• Thermal Management: If installed in an enclosure, ensure proper ventilation to prevent ambient temperature from exceeding the unit's rated operating threshold.
• Wiring: Connect main power inputs and motor outputs according to the terminal markings. Ensure connections are tightened to specified torque values.
• Grounding: Secure the device to a common ground point within the control panel to satisfy EMC requirements and safety standards.
• Configuration: Utilize the built-in display to set parameters such as ramp-up time, ramp-down time, and current limit based on the motor's specific load requirements.
