The Schneider ATS22C11Q soft starter is ideal for motors rated at 30 kW at 230 V and up to 55 kW at 400 V and 440 V, offering precise control for smooth acceleration and deceleration. Designed for use in pump and fan systems, it helps reduce mechanical stress and energy spikes during startup. It includes dual relay outputs (R1 & R2) capable of signaling critical states like running, trip, alarm, and not ready. Its integrated RS485 serial interface with an RJ45 connector supports real-time communication with automation systems like PLCs or SCADA platforms.
Engineered for demanding industrial environments, the ATS22C11Q complies with IEC 60068-2-27 shock resistance (15 g), has IP20 protection, and meets pollution degree 2 standards. It operates efficiently across a voltage range of 230–440 V and frequency range of 45–66 Hz, with supply limits from 195 to 484 V. The unit dissipates only 73 W under standard loads and consumes 20 W in steady-state mode. Compact in design—150 mm wide, 356 mm high, 229.5 mm deep—and weighing 18 kg, it's well-suited for industrial control panels requiring vertical mounting within ±10°.
When variable speed control is required in addition to soft starting, the Schneider Altivar 610 15kW Variable Speed Drive ATV610D15N4 provides advanced functionality for HVAC systems, pumping stations, and manufacturing processes. It allows real-time torque and speed adjustments to meet dynamic load demands efficiently.
The ATV610D15N4 includes built-in EMC filters, diagnostics, and Schneider EcoStruxure compatibility for remote monitoring and predictive maintenance. It ensures stable performance under harsh industrial conditions, making it suitable for critical motor-driven operations.
Whether you need precise motor start control with the Schneider ATS22C11Q or adaptive speed regulation with the Altivar 610 ATV610D15N4, these VFD solutions help improve equipment life, reduce energy usage, and maintain operational reliability using ATS22C11Q.
