The Schneider Altistart ATSU01 Soft Starter is a compact and efficient solution for starting and stopping three-phase asynchronous motors.
The Altistart U01 is a soft start/soft stop unit for 3-phase asynchronous motors. It is designed primarily for combinations with TeSys U starter-controllers.
- It can be used for a motor rated power up to 11kW or 15hp for 3-phase (200V to 480V AC) and up to 22A rating. It is 45mm wide, this makes it one of the smallest soft starters on the market.
- It can be installed nearly everywhere. It features an Integrated bypass, this reduces noise and decreases heat dissipation. Its protection index is IP20.
- It weighs 0.49kg and its dimensions are, 45mm wide, 314mm high, 170mm deep.
- The Altistart U01 is designed for the following simple applications like conveyors, conveyor belts, pumps, fans, compressors, automatic doors and gates, small cranes and belt-driven machinery.
- It complies with standards IEC/EN 60947-4-2, and carries UL, CSA, C-Tick, and CCC certifications, and CE marking. It can be easily combined with a TeSys U controller by means of the power connector VW3G4104.
- It is easy to install on a DIN rail. Altistart 01 combines simplicity with easy cabling, fast configuration and efficiency.
- Reduced machine wear and minimized maintenance time will optimize operations.
- Together with TeSys Model U, it provides a unique motor starter solution.
Features
- Soft Start/Soft Stop: Provides smooth acceleration and deceleration of motors, reducing mechanical stress and extending the life of your equipment.
- Designed for TeSys U: Seamlessly integrates with TeSys U starter-controllers, creating a compact and coordinated motor control solution.
- Wide Voltage Range: Supports a broad range of voltages, making it adaptable to various power supplies.
- Compact Size: Its small footprint allows for easy installation in tight spaces or within existing enclosures.
- Integrated Bypass: Features a built-in bypass contactor that engages once the motor reaches full speed, minimizing heat generation and energy consumption.
- Easy to Use: Simple setup and operation with clearly labeled terminals and adjustable parameters.
