In addition to soft starting and soft ramp down, the solid state SIRIUS 3RW44 soft starters provide numerous functions for higher level requirements. They cover a performance range up to 710 kW (at 400 VAC) in the inline circuit and up to 1200 kW (at 400 VAC) in the inside delta circuit. The 3RW44 soft starters are characterized by a compact design for space saving and clearly arranged control cabinet layouts. For optimized motor starting and stopping the innovative SIRIUS 3RW44 soft starters are an attractive alternative with considerable savings potential compared to applications with a frequency converter. The new torque control and adjustable current limiting enable the high feature soft starters to be used in nearly every conceivable task. They guarantee the reliable avoidance of sudden torque applications and current peaks during motor starting and stopping. This creates savings potential when calculating the size of the switchgear and when servicing the machinery installed. Be it for inline circuits or inside delta circuits the SIRIUS 3RW44 soft starter offers savings especially in terms of size and equipment costs. Combinations of various starting, operating and ramp down possibilities ensure an optimum adaptation to the application specific requirements. Operation and commissioning can be performed with the menu controlled keypad and a menu prompted, multi-line graphic display with background lighting. The optimized motor ramp up and ramp down can be effected quickly, easily and reliably by means of just a few settings with a previously selected language. Four key operation and plain text displays for each menu point guarantee full clarity at every moment of the parameterization and operation.
