Siemens Soft Starter, 32A Current Rating, 15kW Power Rating - SIRIUS Series - 3RW4027-1BB04
Choose this soft starter from Siemens to safely power your 3-phase asynchronous industrial motors. It works by regulating the energy needed for a motor to start up, letting it slowly ramp up to full speed and reducing the risk of surges and overloads that can occur with a full power supply. The starter has a thermoplastic housing that provides thermal and impact resistance, making it suitable for use in harsh environments. It delivers up to 15kW of power to your motors, so it's a practical choice for heavy-duty use such as factory automation applications.
• IP20 rating indicates protection from fingers and objects larger than 12mm in size
• Voltage rating of 400V AC is suitable for low-voltage applications
• Narrow width of 45mm for space-efficient installation in tight enclosures
• Integrated remote reset mechanism lets you clear faults from a distant location for convenience
What maintenance does this soft starter need?
You should look after this soft starter by regularly inspecting its terminals for loose or broken screws to reduce the risk of arcs and short circuits.
