ATSU01N209LT

The Schneider Electric ATSU01N209LT is a soft starter specifically engineered for asynchronous AC motors. It incorporates an internal bypass function that aids in maintaining operational efficiency. The starting time can be fine-tuned between 1 second and an impressive 10 seconds, with specific adjustable intervals of 1s for 100 starts, 5s for 20 starts, and 10s for 10 starts.

This model utilizes a voltage ramp method for initiating system operations, providing a smoother transition during the start phase. It supports a motor power of 1.5 kW at 230 volts and escalates to 4 kW when operating at 400 volts, catering to a range of motor sizes. The rated current for the ATSU01N209LT is set at 9 A, ensuring sufficient capacity for various applications. This starter operates within a supply voltage range of 200 to 480 volts, with manageable tolerances of -10 to +10%.

Connections are facilitated through a screw connector for the control circuit, accommodating rigid wires from 0.5 to 2.5 mm² (AWG 14). The power circuit employs a 4 mm screw clamp terminal, which supports rigid cables ranging from 1 to 10 mm² (AWG 8). The device is intended for vertical installation, with slight variations of +/- 10 degrees allowable.

In terms of durability, the ATSU01N209LT has an IP20 protection degree, ensuring it is suitable for environments where dust and dirt are minimal. Its lightweight design, at just 0.34 kg (or 0.75 pounds), makes it easy to integrate into existing setups. With overall dimensions measuring 234 mm in height, 45 mm in width, and 150 mm in depth, this soft starter is compact yet effective, featuring an assembly style that includes a heat sink for enhanced temperature regulation.
