Schneider Electric ATS22D17Q Altistart 22 Soft Starter

Overview

The Schneider Electric ATS22D17Q is a 17 A soft starter from the Altistart 22 range, designed to provide controlled, progressive starting and stopping for asynchronous motors from 4 to 7.5 kW on a 230–440V power supply with 230V control voltage. Rather than switching full line voltage directly onto the motor, the ATS22D17Q ramps voltage and current gradually, reducing mechanical stress on couplings, belts, and driven equipment while cutting inrush current draw on the supply network.

With fast quotation turnaround and technical support, Seven Star LLC proudly supplies the Schneider Electric ATS22D17Q to industrial facilities, water utilities, and OEM panel builders throughout the Sultanate of Oman and the wider GCC. Engineers in Muscat, Sohar, and Salalah can source Altistart 22 soft starters through Seven Star LLC, with lead time confirmed at quotation, for both new installations and legacy equipment replacement.

Operating Principle of the Schneider Electric ATS22D17Q

The ATS22D17Q uses thyristor-based phase-angle control on two or three motor phases to progressively increase the effective RMS voltage applied to the motor during starting, following a configurable voltage ramp or current-limit profile. This soft-start technique avoids the mechanical shock and current spike associated with direct-on-line starting, instead allowing torque to build smoothly as the motor accelerates toward rated speed, which is particularly valuable for pumps, fans, and conveyors coupled to belts, gearboxes, or fluid systems sensitive to sudden torque application.

On stopping, the ATS22D17Q can apply a controlled deceleration ramp instead of an abrupt line disconnection, which is especially useful on pumping systems where sudden stops can cause water hammer and associated pipework damage. Once the motor reaches full speed, the ATS22D17Q’s internal bypass contact can close to remove the thyristors from the current path, reducing heat dissipation and improving overall system efficiency during normal running.

Engineering Design of the Schneider Electric ATS22D17Q

The Schneider Electric ATS22D17Q uses a slim, compact form factor characteristic of the Altistart 22 range, reducing control-panel footprint compared with older soft-starter designs and simplifying spare-parts stocking for maintenance teams managing multiple motor circuits. The unit is configured through an integrated keypad and display, with parameters covering starting torque, current limit, ramp time, and stopping mode accessible without external software in most standard applications.

Protection functions built into the ATS22D17Q include thermal overload protection, phase-loss detection, and motor-stall protection, reducing the need for separate protection relays in simple motor circuits. Terminal wiring accommodates standard control inputs for run/stop commands and a relay output for fault or run status signaling, while the compact enclosure supports panel or DIN-rail mounting depending on the installation.

Key Features of the Schneider Electric ATS22D17Q

The Schneider Electric ATS22D17Q brings reliable, field-proven soft-starting technology to mid-range motor applications in a compact package.

• Rated 17 A for asynchronous motors from 4 to 7.5 kW on a 230–440V power supply.
• Thyristor-based phase-angle control delivers smooth acceleration and reduced inrush current.
• Controlled deceleration ramp helps prevent water hammer on pumping applications.
• Slim form factor reduces control-panel footprint and simplifies spare-parts stocking.
• Integrated thermal overload and phase-loss protection reduce the need for separate protection relays.
• Reduces mechanical stress on couplings, belts, and gearboxes during motor starting.
• Lowers hearing discomfort for operators by eliminating the mechanical bang of direct-on-line starting.
• Simple keypad configuration allows fast commissioning without external software.

Industrial Applications

The Schneider Electric ATS22D17Q Altistart 22 soft starter is widely applied on pumps, fans, conveyors, and compressors where smooth starting extends the service life of mechanical transmission components and reduces stress on the electrical supply network. In Oman’s water and wastewater sector, and across industrial estates in Sohar and Salalah, the ATS22D17Q is commonly specified for booster pump stations and process fans where controlled starting and stopping directly reduces maintenance costs and pipework wear associated with sudden pressure changes.

With engineering support in Muscat, Seven Star LLC distributes the ATS22D17Q to utilities, industrial end users, and panel builders across Muscat, Sohar, and Salalah, supporting both greenfield motor-control installations and retrofit projects replacing older electromechanical starting equipment. Regional buyers benefit from genuine Altistart hardware and technical sizing guidance suited to Oman’s industrial and utility infrastructure.

Selection Guide & Sizing

Specify the ATS22D17Q for motors up to 7.5 kW (17 A) on 230–440V supplies. For larger loads step up to the ATS22D37Q (37 A) or ATS48 soft starter range. Match the starter to the motor nameplate current, not just power, and allow 10% headroom for hot-restart duty. Seven Star LLC supplies the matching bypass contactor kit, current transformers, and IP54 remote terminal for panel integration.

Dimensions & Mounting

The ATS22D17Q mounts on a 35 mm DIN rail or directly to the panel backplate using M4 screws. Allow 50 mm top and bottom clearance for convection cooling and do not mount above other heat-generating devices. Control wiring uses spring or screw terminals clearly marked on the unit.

Compliance & Certifications

The ATS22D17Q conforms to IEC/EN 60947-4-2 and carries CE, UL, and cUL marks. Soft-start reduces starting current to 2–4× FLC, easing generator and transformer sizing on remote Oman sites.
