3RW3036-1BB14

The SIRIUS 3RW30 soft starters reduce the motor voltage through variable phase control and increase it in ramp-like mode from a selectable starting voltage up to mains voltage. During starting, these devices limit the torque as well as the current and prevent the shocks which arise during direct starts or wye-delta starts. In this way, mechanical loads and mains voltage dips can be reliably reduced.

• Soft starting and smooth ramp-down
• Stepless starting
• Reduction of current peaks
• Avoidance of mains voltage fluctuations during starting
• Reduced load on the power supply network
