CD Automation Soft Starter
CD Automation Soft Starters are designed to drive three phase, three wire, squirrel cage induction motors, providing a reliable, efficient and energy saving solution for the industrial use of electric motors.
Three different family’s are available:
- STB: Basic model (3 wire)
- STO: Medium performance model (3 wire)
- STE: Enhanced soft start performance model (3 & 6 wire)
Soft Starter Selection
- Start from application table on the right Example (below in case you are looking this page with a mobile device): Agitator 50A the suggested start current is 4 times FLC (full load current 50A)
- Select model from table at the bottom page
- Go on column HEAVY (4) and nominal current of your motor must be equal or less than the value (In our example is 55A)
- If selected model is STB your soft starter is STB075
- If you want to receive Soft Starter already configured follow the code below.
