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 supplies 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.
