Product Positioning

The 3RW4047-1BB14 is a Siemens SIRIUS 3RW40 series S3 housing soft starter with a rated current of 98A. It supports a wide voltage range of 110 to 230V AC/DC and is suitable for existing distribution panels to directly reuse power wiring.

Core Product Advantages and Features

Wide range control power supply

The control circuit supports 110 to 230V AC/DC, eliminating the cost of setting up a separate low-voltage control power supply.

S3 casing 98A rated

The rated current is 98A at 50°C, which corresponds to a motor of approximately 30kW at 230V and approximately 75HP at 460V.

Adjustable current limiting startup

Adjust the starting current limit value according to the motor characteristics to reduce the impact on the mechanical structure at the moment of starting.

Built-in motor overload protection

Integrate overload monitoring mechanisms to simplify the configuration requirements of protection components within the control panel.
