Q1: What is the Siemens 3RW5146-1XC14?
It is a SIRIUS 3RW5 series soft starter rated for 370 A and 200 kW (standard circuit at 400 V). It features integrated motor overload protection, an analog output for current monitoring, and screw terminals, but no integrated bypass contactor .
Q2: Does this soft starter include an integrated bypass?
No. This variant (1XC14) does not include an integrated bypass contactor. An external bypass contactor must be installed for continuous operation after motor startup .
Q3: What is the motor power rating?
In standard circuit at 400 V, the rating is 200 kW. In internal delta connection at 400 V, the rating increases to 355 kW .
Q4: Does this soft starter have motor overload protection?
Yes. It includes integrated electronic motor overload protection with adjustable trip classes: Class 10A, 10E, 20E, or OFF .
Q5: What is the analog output used for?
The analog output provides a signal proportional to motor current, allowing the control system to monitor load conditions in real time without a separate current transducer .
Q6: What is the control supply voltage?
The control supply voltage is 110–250 V AC, 50/60 Hz .
Q7: What is the main circuit voltage range?
The main circuit voltage range is 200–480 V AC .
Q8: What is the protection class and weight?
The soft starter is IP00 rated with a net weight of approximately 9.6 kg .
Q9: Can I add communication modules to this soft starter?
Yes. The 3RW5 platform supports optional PROFINET, PROFIBUS, or Modbus RTU communication modules (e.g., 3RW5980-0CS00 for PROFINET), as well as HMI modules for local operation .
Q10: What is the country of origin?
China .
Q11: What should I verify before ordering?
Always verify the exact part number (3RW5146-1XC14 for 370 A with analog output, no bypass), confirm your motor full-load current does not exceed 370 A at 40°C, ensure your supply voltage matches (200–480 V AC), and determine whether you need an external bypass contactor for continuous operation. If integrated bypass is required, select the 1XC24 variant instead.
