Siemens 3RW3026-1BB14 | SIRIUS Soft Starter

Overview:

The Siemens 3RW3026-1BB14 is a SIRIUS series soft starter engineered to facilitate the smooth startup of three-phase asynchronous motors. By gradually increasing the motor voltage, it minimizes mechanical stress and reduces inrush current, thereby extending the lifespan of both the motor and connected equipment. This soft starter is suitable for motors rated up to 11 kW (15 HP) at 400 V, handling operational currents up to 25 A. It operates within a supply voltage range of 200–480 V AC and accepts a control voltage of 110–230 V AC/DC. The device is designed for easy integration with screw terminal connections and is mountable on standard 35 mm DIN rails.

Key Features:

• Smooth Motor Startup: Reduces mechanical wear and electrical stress by controlling voltage ramp-up during motor startup.
• Integrated Bypass Contacts: Enhances energy efficiency by reducing power loss once the motor reaches full speed.
• Compact Design: Space-saving dimensions facilitate easy installation in control panels.
• Wide Control Voltage Range: Compatible with control voltages from 110 to 230 V AC/DC, offering flexibility in various control schemes.
• Screw Terminal Connections: Ensures secure and straightforward wiring.
