Siemens 3RW3014-1BB14 SIRIUS Soft Starter S00 6.5A 3kW 200-480V

The Siemens 3RW3014-1BB14 is a SIRIUS soft starter in frame size S00, rated at 6.5 A and 3 kW at 400 V / 40°C. It provides controlled motor acceleration via thyristors with an integrated bypass contact that reduces losses once the motor reaches full speed. The control supply accepts 110-230 V AC/DC, and the main circuit operates across 200-480 V AC.

Features and benefits:

• Integrated bypass contact minimises power dissipation once the motor reaches operating speed
• Thyristor-based control delivers smooth, stepless motor acceleration to reduce mechanical stress
• Wide main voltage range (200-480 V AC) covers both 230 V and 400 V network standards
• Dual AC/DC control input (110-230 V) simplifies integration into existing control panels
• Compact 45 mm S00 frame conserves panel space with snap-on or screw mounting
• Fault signal indicated via red display for fast fault identification

Applications:

• Soft starting of 3-phase induction motors up to 3 kW on 400 V industrial networks
• Pump, fan, and conveyor motor control to limit inrush current on startup
• Compact motor control centres and distribution boards where panel space is limited
• Applications requiring reduced mechanical shock during motor ramp-up

Compliant with IEC 60947-4-2. Part of the Siemens SIRIUS range.
