Siemens Soft Starter 3RW3046-1BB14

Siemens 3RW3046-1BB14 is a three-phase SIRIUS soft starter designed to smooth the starting process of electric motors, thereby reducing inrush current and starting torque. 

Specification:

• Product Type : SIRIUS 3RW30 Soft Starter.
• Operational Current (at 40°C) : 80 A.
• Rated Power (at 400V AC) : 45 kW.
• Rated Operational Voltage : 200-480 V AC.
• Control Supply Voltage : 110-230 V AC/DC.
• Mounting Method : Screw and snap-on mounting (DIN rail).
• Dimensions (HxWxD) : Approx. 160 mm x 70 mm x 186 mm.

Key Features:

• Smoother Operation: This soft starter regulates the voltage supplied to the motor to ensure a smooth start, which helps extend the lifespan of the motor and connected mechanical components.
• Integrated Bypass Contact System: The device features an integrated bypass contact system. This means that once the motor reaches full speed, current flows through mechanical bypass contacts, reducing the heat generated by the thyristors and increasing energy efficiency.
• Compact Design: The soft starter has a compact S3 frame size, suitable for space-saving installation in control panels.
