Product Overview
The Schneider ATS480C25Y Soft Starter is an industrial motor-control device designed to provide controlled acceleration and deceleration for compatible AC motor applications. By managing the motor starting process, a soft starter can provide smoother acceleration than an uncontrolled direct-starting method and can help reduce mechanical shock within the driven system.
The ATS480C25Y can be incorporated into industrial motor-control architectures used for pumps, fans, conveyors, compressors, blowers, material-handling equipment, and other motor-driven machinery where controlled starting and stopping are required.
The supplied product information identifies the Schneider ATS480C25Y as a Soft Starter, with dimensions of 380 × 277 × 320 mm and a weight of 18.2 kg.
Because of its relatively large physical size and weight, installation requires particular attention to cabinet construction, mounting strength, cable routing, ventilation, heat dissipation, and service access.

Function and Working Principle
The ATS480C25Y is installed within a motor-control circuit to manage the motor’s starting and stopping process.
A simplified system arrangement is:
Incoming AC Supply
↓
Circuit Protection
↓
ATS480C25Y Soft Starter
↓
AC Motor
↓
Mechanical Load
During startup, the soft starter controls the electrical conditions applied to the motor so that acceleration occurs in a controlled manner.
The general sequence is:
Start Command
↓
Controlled Acceleration
↓
Motor Reaches Operating Speed
↓
Normal Motor Operation
When stopping is required, the selected stopping behavior can control motor deceleration according to the application.
Actual results depend on:
- Motor characteristics
- Motor load
- Supply conditions
- Acceleration settings
- Stopping settings
- Current limitation
- Protection configuration
- Mechanical system characteristics
Why Use ATS480C25Y?
Large industrial motors can produce substantial electrical and mechanical stress during startup. A soft starter provides a controlled method for managing this transition.
Potential benefits include:
- Smoother motor acceleration
- Reduced mechanical shock
- Controlled starting torque
- Reduced stress on mechanical couplings
- Reduced stress on gearboxes and driven equipment
- Controlled stopping
- Improved machine-starting behavior
- Integration with industrial automation systems
The soft starter controls the starting process but does not remove the motor’s inherent electrical requirements.
Role in Industrial Control Systems
The ATS480C25Y can be installed between the incoming power system and the motor.
A typical arrangement is:

Conveyors
Controlled acceleration can reduce sudden belt tension and mechanical shock.
Compressors
A suitable soft-starting process can help manage the mechanical demands associated with compressor motor startup.
Material Handling
Motor-driven machinery can benefit from controlled acceleration and stopping.
Process Equipment
The ATS480C25Y can be incorporated into compatible industrial process machinery requiring controlled motor operation.
Installation Guide
1. Verify the Product Model
Before installation, confirm the complete model number:
Schneider ATS480C25Y
Soft Starter
Do not identify the equipment solely by its appearance. Verify the model marking before connecting any electrical circuit.
2. Verify Motor Compatibility
Collect the motor information before commissioning.
Check:
- Motor voltage
- Motor current
- Motor power
- Motor frequency
- Motor connection
- Motor duty
- Full-load current
- Starting torque

- Starting frequency
The soft starter should be correctly matched to the actual motor and application.
3. Evaluate the Mechanical Load
The mechanical load has a direct influence on starting behavior.
Evaluate:
- Motor inertia
- Load inertia
- Starting torque
- Pump conditions
- Conveyor loading
- Compressor resistance
- Fan inertia
- Frequency of starting
- Required acceleration time
A lightly loaded motor and a heavily loaded motor may require substantially different starting conditions.
4. Inspect the ATS480C25Y
Before installation, inspect the soft starter for:
- Cracked housing
- Damaged terminals
- Mechanical deformation
- Corrosion
- Contamination
- Loose mounting components
- Signs of impact
If obvious physical damage is present, the equipment should not be placed into service until its condition has been evaluated.
5. Verify Cabinet Dimensions and Mounting
The supplied dimensions are:
380 × 277 × 320 mm
The cabinet must provide additional space around the unit for:
- Power cables
- Control cables

- Inspection
- Maintenance
The supplied weight is:
18.2 kg
The cabinet structure and mounting hardware must therefore provide adequate mechanical support.
Do not mount the soft starter on a weak panel or structure that cannot safely support the equipment and connected cables.
6. Consider Thermal Management
Soft starters generate heat during operation and especially during repeated starting cycles.
Cabinet design should consider:
- Ambient temperature
- Internal heat accumulation
- Airflow

Avoid installing the ATS480C25Y immediately adjacent to heat-generating equipment without evaluating the resulting thermal environment.
7. Connect Incoming Power
Connect the incoming supply according to the approved electrical design.
Verify:
- Phase identification
- Cable selection
- Protective devices

Connect the motor according to the approved motor-control design.
Check:
- Motor terminals
- Phase connections
- Motor cable condition
- Grounding
- Motor configuration
- Protective equipment
9. Connect Control Wiring
Depending on the control architecture, control circuits may include:
- Start command
- Stop command
- Run status
- Fault status
- External interlock
- PLC command
- Emergency-stop interface
Control wiring should be clearly identified and routed appropriately.
10. Configure Operating Parameters
Before the first motor start, verify the applicable parameters.
Typical configuration areas may include:
- Motor current
- Starting characteristics
- Acceleration time
- Stopping characteristics
- Deceleration time
