Schneider Altistart U01 ATSU01N212LT Soft Starter

Description

The ATSU01N212LT is a compact Soft Starter from the Altistart U01 range, engineered for the smooth starting and stopping of three-phase asynchronous motors. By regulating the voltage ramp, this device effectively mitigates torque transients and high inrush currents, protecting mechanical components such as belts, chains, and gearboxes. It is designed for motors with a power rating between 2.2 kW and 5.5 kW, operating within a wide voltage supply range of 200V to 480V and a rated operational current of 12 A. Its ultra-compact design is specifically optimized for space-constrained control panels in various industrial sectors.

Installation Guidelines

• Mounting: Designed for standard DIN rail installation. Maintain a vertical orientation to ensure proper heat dissipation.
• Ventilation: Ensure sufficient space around the unit to allow for natural convection; do not obstruct the housing vents.
• Wiring: Verify motor and power supply connections match the required terminal designations. Use appropriate wire gauges to handle the 12 A nominal current.
• Grounding: Secure a reliable chassis ground to the system earth to maintain electrical safety and EMC integrity.
• Adjustment: Use the front-mounted potentiometers to fine-tune the acceleration/deceleration ramp according to the specific load requirements of the motor.
