Features of the soft starter:
The motor can be soft-started, soft-stopped, and soft-stopped.
It can achieve a small impact on the machine-to-power grid.
It is much smaller than the Star-Delta starter and the installation is simple.
Features of the inverter:
The soft starter function is simply available.
It has more maintenance and control functions.
The inverter is used in places where speed regulation and constant pressure change control are required.
Differences:
How do we know which equipment we need for our application? Which equipment you choose depends on how you can handle your needs. If your application requires soft start but not speed control, then a soft starter is the best choice. If speed control is required, an inverter must be used.
In addition, price can be a determining factor in many practical applications. Soft starters are less expensive than frequency converters because they have less control function. If the size of our equipment is the deciding factor, soft starters are usually smaller than most drives.

Delixi electrical components circuit breaker introduction
What is a Circuit Breaker? What is the function of a circuit breaker? How to choose the right circuit breaker in the work? The circuit breaker is what we often call an air switch. Just like a dam that controls the release of water, when the sluice gate is opened, the flow of water is continuous, and when the sluice gate is lowered, it blocks the flow of water.

The difference between Delixi high-voltage circuit breaker and disconnector
The high-voltage circuit breaker (or high-voltage switch) is the primary power control equipment of the substation, which has arc extinguishing characteristics. When the system is in normal operation, it can intercept and connect the no-load and load currents of lines and various electrical equipment. When there is a problem in the system, it can quickly block the fault with the cooperation of relay maintenance.
