سوفت ستارتر سيمنس
SIRIUS 3RW30 soft starters reduce the motor voltage through variable phase angle control and increase it from a selectable starting voltage up to the mains voltage within the ramp time. They limit the starting current and torque, reduces the stress on the connected equipment, resulting in lower wear and therefore longer periods of trouble-free production.
