The Siemens 3RW3018-1BB14 soft starter is a compact and efficient solution designed to optimise the start-up process of three-phase motors. This device is engineered to reduce the mechanical stress on motor control systems, making it an ideal choice for a wide range of industrial applications. With a rated operational current of 17.6 A and the capability to manage motors with a power output of up to 7.5 kW at 400 V, it is suitable for a variety of medium-duty tasks.

The soft starter operates within a supply voltage range of 200 to 480 V AC and can handle control supply voltages of 110 to 230 V AC/DC, providing flexibility for integration into diverse electrical setups. Its compact dimensions, 95 x 45 x 150 mm, allow for space-saving installation, and the screw terminals ensure a secure and reliable connection.

This model comes equipped with an integrated bridging contact system and thyristors, yet it does not include intrinsic device protection or motor overload protection, allowing for customised protection schemes to be implemented as required. The absence of an internal bypass circuit means that the device is optimised for applications where soft starting and stopping are necessary to prevent mechanical shocks and electrical peaks.

The 3RW3018-1BB14 is designed for straightforward installation with options for screw and snap-on mounting, and it can be positioned with a degree of flexibility, thanks to its rotatable and tiltable mounting options. It is also designed to work reliably in a wide range of ambient temperatures, from -25 to +60 degrees Celsius, ensuring consistent performance in varying environmental conditions.

With its robust construction and adherence to international standards, including a protection class of IP20, this soft starter is a durable and reliable component for managing the demands of starting electric motors.
