Model Interchange Guide for Schneider ATS480 Series and Soft Starters of Other Brands

To meet the needs of equipment replacement and multi-brand selection, this guide provides a precision model interchange comparison table for Schneider ATS480 series and soft starters of mainstream brands (เอบีบี, ซีเมนส์, Rockwell, อีตัน), covering the full current range (17A-1200A), with key selection notes and technical points attached.

1. Series Positioning of Mainstream Brands

1. Complete Model Interchange Comparison Table (in ascending order of current)

III. Key Notes for Model Interchange

1. Current Matching Principle

Standard load: Rated current of the alternative model ≥ Rated current of the motor

Heavy-duty application: Rated current of the alternative model ≥ 1.25 × Rated current of the motor

690V system: Pay attention to the power-current conversion relationship (Power ≈ Current × 0.53)

2. Consistency Check of Key Parameters

3. Adaptation for Special Applications

Water pumps: Confirm the built-in pump control curve function.

Fans: Check the fan-specific control mode.

Compressors: Verify the torque control accuracy and starting current limiting capability.

Heavy-duty start: Ensure the alternative model supports derating (เช่น, 1.25 times the motor current).

4. Technical Differences between Brands

ABB PSTX: Equipped with a built-in bypass contactor, no additional installation required.

Siemens 3RW: High integration of SIRIUS thermal overload protection, with closer cooperation with contactors.

Rockwell 150-C: Superior DeviceNet communication, suitable for Allen-Bradley systems.

Eaton DS7: Larger adjustable range of soft stop time, suitable for long-distance conveying systems.

1. Replacement Implementation Steps
2. Parameter recording: Record the key parameters of the original ATS480 (starting current limit, start-up time, soft stop time, protection threshold, ฯลฯ).
3. Model confirmation: Select the corresponding alternative model according to the current and application scenario.
4. Installation adaptation: Confirm the compatibility of installation dimensions, heat dissipation space and connection terminals.
5. Parameter migration: Set the original parameters to the new equipment accordingly.
6. Function test: Conduct no-load test of start/stop functions and load test to verify the protection mechanism.
7. Communication configuration: Configure the corresponding communication protocol to ensure compatibility with the upper system.
