Product Details

I. Product Overview

The Schneider ATS48D75Q is a soft starter from the Altistart 48 series manufactured by Schneider Electric of France, model ATS48D75Q. This soft starter has a line rating of 69A, control voltage of 220V, supply voltage 230~415V, suitable for 15~30kW in heavy duty and 18.5~55kW in standard duty three-phase asynchronous motors, used for soft starting and soft stopping, achieving smooth motor start, reducing starting current and avoiding mechanical shock.

The Altistart 48 (ATS48) is Schneider Electric's premium soft starter series, designed for heavy industry and pump applications, covering 4~1200kW. This series features TCS (Torque Control System), achieving smooth start/stop via both voltage and torque control, supporting standard and heavy duty applications. The ATS48D75Q has utilization category AC-53A, supports optional external bypass, and provides comprehensive motor protection.

The ATS48D75Q is a three-phase application with protection rating IP20. This soft starter can be connected in the motor supply line (inline) or in the motor delta (inside delta), with inside delta connection supporting up to 55kW. Communication is Modbus (RS485, RJ45, baud rate 4800/9600/19200bps). It supports 5 logic inputs (including PTC probe 750Ω), 2 logic outputs and 3 relay outputs (fault, end of start, motor energized), with analog current output 0-20mA/4-20mA. Dimensions 190×235×290mm, net weight 8.3kg. It is widely used in pumps, fans, compressors and other applications.
