We've introduced many advantages of soft starters to you. But how should you choose a soft starter? Today, let's delve into the details and provide some insights.

1. When selecting a soft starter, note whether the load is a standard or heavy-duty load. Choose different types of starters based on the nature of the load.

If the load is a centrifugal pump (fire pump, sprinkler pump, water pump, etc.), it is necessary to utilize the pump control function to minimize the occurrence of system water hammer phenomena caused by liquid flow impact during start-up and shutdown. Therefore, it is essential to use a soft starter equipped with pump control functions, and it is even better if it includes underload protection or phase reversal protection.

In the case of a ventilation fan as the load, utilize the soft start function to reduce belt wear and mechanical shock, and take advantage of the braking torque feature during shutdown.

The loads include mixers, crushers, conveyors, etc., which are started using dual incline and preset low-speed operation to prevent machinery damage.

The load is a conveying equipment that utilizes soft start and preset low-speed functions to achieve smooth start-up and shutdown. Soft braking eliminates the reverse inertia impact on the dragging system caused by free braking, preventing product displacement and liquid overflow.

2. Select the starter based on the motor's rated power, current, and load characteristics. Generally, a soft starter with a capacity slightly greater than the motor's operating current is sufficient. For heavy load applications in cement plants, such as crushers, ball mills, conveyors, long belts, mixers, and fans, it is recommended to use the next higher rating. Also, consider heat dissipation factors appropriately.

3. Additionally, consider whether the protection features are comprehensive.

Overcurrent protection, overvoltage protection, single-phase grounding protection, phase loss protection, three-phase unbalance protection, phase reversal protection, etc. For models without overload protection, an additional thermal relay protection must be installed.
