Product Overview
The Schneider ATS480C41Y Soft Starter is an advanced motor control device designed for the smooth starting and stopping of high-power three-phase AC induction motors. It minimizes the high inrush current and mechanical shock associated with conventional direct-on-line (DOL) motor starting, helping to improve equipment reliability, extend motor service life, and reduce maintenance costs.
Utilizing SCR (Silicon Controlled Rectifier) technology, the ATS480C41Y gradually increases motor voltage during startup and controls voltage reduction during stopping. This allows motors to accelerate and decelerate smoothly, reducing stress on shafts, couplings, gearboxes, belts, pipelines, and driven machinery.
The Schneider ATS480C41Y is suitable for demanding industrial environments including water treatment, mining, cement production, oil and gas, HVAC systems, compressors, conveyors, pumps, crushers, and other heavy-duty motor applications.
According to the supplied product information, the Schneider ATS480C41Y Soft Starter has overall dimensions of 670 × 400 × 314 mm and a shipping weight of 51.4 kg.
