Schneider Electric Altistart Soft Starter 480V AC, 5.5 kW, 3 Phase, DIN Rail Mount, IP20 ATSU01N212LT

Schneider Electric ATSU01N212LT is a high-quality soft starter for 3 phase asynchronous motors with a power rating of 5.5 kW and maximum supply voltage of 480V AC. It is designed primarily to be combined with TeSys model U controller-starters, creating an innovative motor control solution that provides soft start and soft stop capabilities. This enables motors to start gradually and smoothly, reducing mechanical wear and electrical stress.

The soft starter controls two phases of the motor's power supply to limit starting current and provide controlled deceleration, ensuring efficient motor operation. It includes an internal bypass relay which increases efficiency by bypassing the starter components after the motor reaches full speed. The unit mounts easily on a DIN rail and features an IP20 ingress protection rating, making it suitable for industrial and commercial electrical panels.

This model is part of the Schneider Electric Altistart series, known for reliable and flexible motor control products. It supports motor power ratings from 0.75 kW up to 15 kW, with supply voltages ranging between 200 V and 480 V AC at 50/60 Hz. Note that the starter requires a separate external 24V power supply for control functions.

The compact dimensions of 113 mm length, 45 mm width, and 154 mm depth facilitate installation in tight panel spaces. The product complies with multiple international safety and performance standards including CE, UL, and IEC specifications, certifying its quality and safety for industrial use.

Typical applications include industrial automation, HVAC equipment, manufacturing machines, and motor control panels where smooth start/stop capability improves system longevity and operational efficiency. Its modular design when combined with TeSys model U modules allows customization of motor protection parameters and control voltages, enabling easy panel configuration and upgrades.

Enables gradual and controlled motor start to reduce mechanical stress. Internal bypass relay improves efficiency in full-speed operation. Compact DIN rail mounting with IP20 protection rating. Supports 3 phase motors rated at 5.5 kW and 480 V AC supply.
