How do I choose a motor starter?
When choosing a motor starter, you should consider the load, the type of motor, and the network before deciding which one is best for you. Soft Starters: Soft starters steadily ramp up the speed of a motor to prevent large current surges and to minimize the amount of wear on electrical contacts in the system.
How do you size a soft starter?
Soft starter sizing is determined by the horsepower or kW rating of the motor, coupled with the mains operating voltage. In an established installation that uses a NEMA-rated starter, a replacement soft starter may be selected based on the NEMA size of the starter.
