We are pleased to announce the immediate availability of the Siemens SIRIUS 3RW5074-6AB14 soft starter, a powerful device engineered for reliable motor control in industrial applications. This 3-phase AC soft starter supports input voltages from 200 to 480V and is designed for use with motors ranging from 5.5kW to 160kW. The unit features a rated current of 315A and offers comprehensive protection functions including electronic overload, phase loss, short circuit, and overheat protection. It measures 389mm × 214mm × 337mm and weighs 7.3kg, making it suitable for integration into control panels and machine control systems where space is at a premium.
Key Features
The 3RW5074-6AB14 delivers exceptional performance with a wide operating temperature range of –25°C to +60°C, ensuring reliable operation in harsh industrial environments. It features a voltage ramp soft start function with adjustable acceleration time from 0 to 20 seconds, limiting start-up current to 3–5 times the rated value and reducing grid voltage fluctuations. The unit also includes a pump control mode with an “S”-shaped acceleration curve to eliminate water hammer effects in piping systems. Additional features include a current limit function adjustable from 130% to 700% of the rated current, Modbus RTU and PROFINET communication protocols, and a protection rating of IP20 (IP41 optional). The soft starter is CE, UL, and CSA certified, ensuring compliance with global standards.
