4、 Selection and procurement suggestions

1. Key selection points

Load type: Confirm that the motor is a three-phase squirrel cage asynchronous motor, and adjust the parameters according to the load characteristics (constant torque/variable torque).

Voltage matching: Check the grid voltage and the rated voltage range of the soft starter to avoid overvoltage/undervoltage operation.

Protection requirements: Select additional protection functions (such as explosion-proof and high-temperature adaptation) based on the industrial environment.

2. Market competition comparison

Differences from the ATS22 series: The ATS48C25Q supports higher power (132kW vs. ATS22's 400kW upper limit), but has a more compact size, making it suitable for space constrained scenarios.

Compared with ABB PSE series, Schneider products have more advantages in communication protocol compatibility (such as Ethernet) and cascade control function.

Schneider ATS48C25Q soft starter has become a benchmark product in the field of industrial motor control due to its precise torque control, comprehensive protection functions, and intelligent communication capabilities. Whether it is pumps, fans or transmission systems, it can provide stable and efficient starting solutions, helping enterprises reduce operation and maintenance costs and improve production efficiency.
