Siemens Soft Starter 3RW3014-1BB14

The Siemens 3RW3014-1BB14 soft starter is a compact SIRIUS device designed for the smooth starting of standard three-phase asynchronous motors up to 3 kW (at 400 V). It works by gradually increasing the motor voltage to reduce starting current peaks and torque, thereby protecting the network and connected mechanical components. 

Specification: 

• Product Range : SIRIUS 3RW30.
• Frame Size : S00.
• IP Rating : IP20 (dust protection, indoor use only).
• Connection Type : Screw terminals.
• Dimensions (H x W x D) : 95 x 45 x 150 mm.

The device controls the motor voltage through variable phase angle control, providing stepless starting and smooth ramp-down, which prevents mechanical shocks and reduces wear on the equipment.
