Schneider Electric Altistart 22 Soft Starter 3-Phase 200-480VAC 17A 7.5kW 220VAC Control

The Schneider Electric Altistart 22 is a robust and reliable soft starter engineered for the controlled starting and stopping of three-phase asynchronous motors. Designed to operate within a voltage range of 200-480VAC, this device effectively manages motor acceleration and deceleration to prevent mechanical shocks and reduce electrical surges on the power grid. By providing a smooth transition during motor startup, it helps extend the operational lifespan of mechanical components such as belts, gears, and couplings while maintaining high performance in demanding industrial environments.

Advantages

This soft starter offers significant benefits by minimizing the high inrush currents typically associated with direct-on-line starting. Its integrated bypass contactor design ensures energy efficiency during steady-state operation, reducing heat dissipation within the control cabinet. The compact footprint allows for space-saving installation in electrical panels, while the advanced internal protection features safeguard the motor against thermal overload and phase imbalance, ensuring consistent and safe operation throughout the motor's lifecycle.

Suitable for

• Centrifugal pumps and hydraulic systems
• Industrial fans and ventilation units
• Compressors and vacuum pumps
• Conveyor belts and material handling equipment
• Mixers and agitators

This device may not be suitable for applications requiring high starting torque, such as heavy-duty crushers or loaded conveyors that need immediate full-load acceleration. It is also not intended for use in single-phase motor applications or systems where variable speed control is required, as this unit is strictly designed for soft starting and stopping functions.

Key specifications

• Rated operational current: 17A
• Power rating: 7.5kW at 400V
• Supply voltage range: 200-480VAC
• Control circuit voltage: 220VAC
• Phase count: 3-phase
• Integrated bypass: Yes

Installation should be performed by qualified personnel in accordance with local electrical regulations. The unit is typically mounted on a DIN rail or backplate within a ventilated enclosure. After physical installation, the control wiring for the 220VAC input and the motor power cables must be connected securely. Configuration of the starting parameters, such as ramp-up time and current limit, is performed via the integrated interface to match the specific requirements of the connected motor.

What to consider before purchase

• Verify that the motor's full-load current does not exceed the 17A rating of the soft starter.
• Ensure the 220VAC control voltage is available in your control cabinet.
• Confirm that the supply voltage matches the 200-480VAC range.
• Check the environmental conditions to ensure the enclosure provides adequate cooling.

For optimal performance and longevity, ensure the soft starter is installed in an environment with adequate ventilation and that all electrical connections are tightened to the manufacturer's specified torque settings. Regularly inspect the unit for dust accumulation to maintain effective heat dissipation.
