10. How does the integrated bypass feature of the ATS48D38Y benefit operation?

The integrated bypass function of the SCHNEIDER ATS48D38Y offers significant energy savings. Once the motor reaches its operational speed, the bypass contactor closes, allowing the motor to run directly on the line power. This bypasses the soft starter's internal power electronics.

This bypass operation reduces heat generation within the soft starter, as the power electronics are no longer conducting current at full motor speed. Consequently, this leads to increased efficiency and can prolong the lifespan of the starter itself by reducing thermal stress.

Furthermore, bypassing the soft starter during continuous operation minimizes voltage drop across the starter. This ensures the motor receives full line voltage for optimal performance and efficiency when it is not in the starting or stopping phase.
