by Siemens

OverviewThe Siemens 3RW3026-1BB14 SIRIUS Soft Starter offers an advanced solution for managing the ramp-up of three-phase asynchronous motors. This device precisely controls the gradual increase of motor voltage, effectively minimizing damaging mechanical strain and significantly lowering inrush current peaks during activation. This leads to a considerable extension of the operational lifespan for both the motor and all connected machinery, resulting in reduced upkeep expenses and improved system dependability. This particular model is ideal for motors up to 11 kW (15 HP) at 400 V, capably handling continuous operational currents up to 25 A. It delivers broad compatibility with a supply voltage range of 200–480 V AC and a flexible control voltage of 110–230 V AC/DC. Designed for practical use, the 3RW3026-1BB14 seamlessly integrates into existing setups using robust screw terminal connections and is optimized for quick mounting on standard 35 mm DIN rails, ensuring a straightforward installation process.Key Features Optimized Motor Startup: Provides accurately controlled voltage ramp-up to ensure a smooth motor start, thereby minimizing mechanical wear, reducing stress on the power supply, and preventing sudden jolts. Integrated Bypass Contacts: Increases energy efficiency by bypassing the thyristors once the motor reaches full speed, thus lowering heat dissipation and power usage. Space-Saving Compact Design: Engineered with a minimal footprint (125 mm H x 45 mm W x 150 mm D), allowing for efficient use of space within control panels and electrical enclosures. Broad Control Voltage Compatibility: Offers exceptional adaptability with a wide control voltage range of 110–230 V AC/DC, facilitating integration into diverse control schemes and global applications. Robust Screw Terminal Connections: Ensures fast, secure, and dependable electrical wiring, simplifying installation and reducing downtime. DIN Rail Mountable: Built for easy and secure mounting on standard 35 mm DIN rails, enabling quick integration into industrial control systems. Enhanced Equipment Longevity: By decreasing mechanical shock and electrical stress during startup, this soft starter significantly contributes to the extended operational life of motors and machinery. Technical Specifications Product Type: SIRIUS Soft Starter Part Number: 3RW3026-1BB14 Motor Rating: 11 kW (15 HP) at 400 V Operational Current: 25 A at 40°C Supply Voltage: 200–480 V AC Control Voltage: 110–230 V AC/DC Frequency: 50/60 Hz Connections: Screw terminals Mounting: 35 mm DIN rail Dimensions (H x W x D): 125 mm x 45 mm x 150 mm Weight: Approximately 0.616 kg Protection Rating: IP20 Operating Temperature Range: -25°C to +60°C Applications Pumping Systems: Effectively prevents hydraulic shock (water hammer) and protects impeller and piping components by ensuring a smooth, controlled startup of pump motors. This extends pump lifespan and reduces maintenance frequency. Conveying Systems: Ensures consistent acceleration, dramatically reducing mechanical stress on belts, gears, and drive components, leading to quieter operation and fewer unplanned stops. HVAC Systems: Facilitates gentle and gradual startup of fans and compressors, which minimizes wear on mechanical components, reduces current surges, and enhances overall system reliability and comfort. Material Handling Equipment: Improves operational efficiency and safety by reducing mechanical shocks during the startup of hoists, cranes, and other equipment, protecting both the machinery and the conveyed materials. Wood Processing Machinery: Ensures a controlled and soft start for saws, planers, and other high-inertia loads, reducing operational vibrations and improving precision. Textile Machines: Provides smooth acceleration for critical mechanisms, preventing sudden jerks that could damage delicate materials or machinery.
