Product Protections:

◆ 8xIn over current protection

◆ 5-8. 5xin Continued Overcurrent Protection

◆ Over load Protection with classes 10A, 10, 20 and 30

◆ Three phase current imbalance Protection.

Typical wiring of softstarter:


◆ Y Wiring Mode

1

When using the external mode of SSR, the SSR power module is connected between the power source and the motor.

Caution: The motors with three terminals can only use the external wiring mode. The rated current of the soft starter in the external mode is selected according to the rated current of the motor.


◆ Internal △ Wiring

2

When using the SSR internal wiring mode, the SSR power module is connected to the motor winding in series. The current of the power module is phase current, which is 1/1. 732 of line current.

Caution: The internal wiring mode can only be applied to motors with six terminals. The rated current of the internal wiring soft starter is selected according to the 1/1. 732 of the rated current of the motor.
