Product Positioning

The 3RW4422-3BC44 is a soft starter model in the SIRIUS 3RW44 series with spring-loaded terminals for the control circuit. Its rated current is the same as the screw-terminal models in the same series, making it suitable for control panel applications that require quick wiring.

Core Product Advantages and Features

Spring-loaded terminal design

The control circuit uses spring-loaded (screwless) terminals, which can shorten wiring construction and maintenance time.

15kW standard wiring capacity

With standard wiring at 400V, it can drive a 15kW three-phase motor, suitable for small and medium-sized equipment.

Delta connection upgraded to 22kW

With the Inside-Delta wiring method, the driving power can be increased to 22kW.

Built-in bypass connection

After startup, the bypass is automatically switched on to reduce heat generation and save energy.
