ATS22D17Q — Schneider Electric Altistart 22 Softstarter
The Schneider Electric Altistart 22 is a compact softstarter covering 6 A to 1200 A for three-phase motors on 208–690 V supply, providing smooth motor starting and stopping to eliminate the mechanical stress and current inrush of direct-on-line starting. The ATS22 uses progressive torque control during starting — adjusting voltage in proportion to the required torque profile — which delivers smoother starting performance than basic voltage-ramp softstarters, especially on high-inertia loads and pumping systems where pressure surge elimination is critical. The built-in bypass contactor on single units and an external bypass option for larger ratings ensure that the drive thyristors carry full motor current only during the starting and stopping phases, eliminating the heat generation and energy loss of continuously powered thyristors during steady-state running.
The ATS22 incorporates comprehensive motor and softstarter protection including electronic thermal overload with class selection, phase loss, phase imbalance, under-voltage, and thermistor input for direct motor temperature monitoring — protection functions that replace a separate motor protection relay in most standard applications. The RS485 Modbus RTU communication port built-in enables remote control and monitoring from a PLC or SCADA system, reporting starting current peaks, motor thermal state, and fault history to central control systems. The ATS22's 50°C continuous ambient rating without derating covers Saudi Arabia's harshest plant room conditions.
The Altistart 22 Saudi Arabia market covers the full range of motor starting applications from light commercial to heavy industrial. HVAC fan and pump motors across Saudi commercial buildings use the ATS22 to eliminate current inrush that triggers distribution transformer overloads and voltage flicker on shared supply circuits. Industrial applications at MODON facilities use the ATS22 for compressor, pump, and conveyor starting where mechanical drive components are protected from the torque spikes of DOL starting. Desalination and water treatment facilities use ATS22 softstarters on large pump motors to eliminate the water hammer that damages pipework during DOL starting.
Razz Middle East stocks ATS22 softstarters from 6 A to 370 A across the standard current range for immediate delivery. Our engineers provide motor starting parameter optimisation, bypass contactor sizing, and Modbus integration commissioning for pump station and industrial motor starting projects across Saudi Arabia.

Key Features & Benefits
- Progressive torque control starting mode adjusts voltage to maintain constant torque profile during acceleration, providing smoother starting on high-inertia loads than basic voltage-ramp softstarters and eliminating current peaks that cause supply voltage flicker.
- Built-in bypass contactor eliminates continuous thyristor power dissipation during running, improving softstarter efficiency and extending thyristor service life compared to designs without integrated bypass.
- Electronic thermal overload with motor class selection (class 5 to 30) replaces the separate overload relay in standard motor starting panels, reducing component count and simplifying panel wiring.
- Modbus RTU communication built-in enables remote starting current monitoring, motor thermal state reporting, and fault history access from PLC or SCADA systems without additional communication modules.
- Deceleration ramp (pump stop) function gradually reduces motor speed before stopping, eliminating water hammer in pump installations and reducing mechanical stress on pipeline fittings and check valves.
- Thermistor input for direct PTC or NTC motor temperature sensor monitoring provides real-time winding temperature protection for high-duty motors operating in high-ambient Saudi environments.
- 50°C continuous ambient operating temperature without derating covers the peak summer conditions in Saudi Arabia's industrial plant rooms, outdoor utility cubicles, and mechanical equipment rooms.
Industrial Applications in Saudi Arabia
- Large centrifugal pump starting at NWC municipal water booster stations, where deceleration ramp eliminates water hammer on pump shutdown in long distribution mains serving Riyadh's residential districts.
- Compressor motor starting at industrial facilities in MODON zones across Riyadh, Jeddah, and Dammam, where reduced starting current eliminates transformer overload and supply voltage flicker on shared distribution circuits.
- HVAC chilled water and condenser water pump starting in commercial buildings and district cooling plants, where progressive torque control eliminates pressure surge and mechanical coupling stress during motor acceleration.
- Conveyor belt motor starting at cement and aggregate processing plants, where smooth torque ramp prevents belt splice failure and extends belt service life compared to DOL starting.
- Fan motor starting in large industrial ventilation systems and dust collection plant, where high-inertia fan starting with controlled torque profile prevents motor current exceeding 350% of rated value.
- Desalination plant seawater pump and brine reject pump starting at SWCC facilities, where deceleration ramp prevents water hammer on the long seawater intake and brine disposal pipelines.
- Refrigeration compressor and screw compressor starting in food cold store and industrial refrigeration facilities, where controlled starting torque protects the compressor's positive displacement mechanism from DOL torque spikes.
