15Kw~400Kw Soft Start Motor Starter 3 Phase With Bypass Contactor

Product Features

Flexible Voltage Compatibility

380V rated or customized, the soft starter here is ideal for various three-phase electrical industrial environments, easily finding room for special voltage demands.

Space-Saving and Compact Size:

With the size of 810x315x320mm, this motor starter is perfectly designed to easily fit into a limited space area, thus becoming ideal for limited space installations.

High Quality and Durable:

Made by ZHENGXI, a well-established brand name, this soft starter meets strict quality control to ensure long-term operation and reliability in the most harsh environments.

Scalable and Flexible Integration:

Easy to be integrated into old systems. Also applicable to update industrial equipment, providing a scalable solution for both small and large-scale operations.

Advantages

Reduced inrush current:
Soft starting minimizes inrush current, which is usually 2-3 times rated current, thereby less voltage fluctuation and minimal impact on other installed equipment. This ensures a stable power supply even at the time of startup.

Grid-friendly operation:

Compared to direct motor starting, which causes heavy grid disturbances, the soft-start process reduces the starting current, damps power oscillations, and stabilizes the grid.

Reduce mechanical stress:

Direct starting subjects the motor to twice its rated torque, accelerating wear and damage on gear and belts. Soft starting reduces this torque by half, which protects your motor equipment from unwanted stress and extends its life.

Smart control and protection:

SZ900-37KW has a powerful CPU and multi-protection options to ensure smooth operation of your equipment even under rugged conditions. The device is also equipped with an easy-to-read digital display for real-time monitoring.

Versatility for many applications:

Great for application on multiple industrial machinery, this starter features multiple start/stop operating modes for versatile motor applications as well as protecting sensitive equipment.

Your ideal soft-start solution

Regardless of whether you’re using fan speed controllers, water supply pumps, or other industrial equipment, this soft starter guarantees safe and efficient motor control across a variety of applications, making it the preferred choice for thousands of professionals.
