Siemens 3RW3018-1BB14 3RW30181BB14 Soft starter Motor power at 400 V 7.5 kW Motor power at 230 V 4 kW 400 V AC Nominal c

The 3RW3018-1BB14 belongs to the SIRIUS-3R soft starter system kits, which have been developed to enable the soft run-up and slow-down of DC motors. It helps the mechanical power transmitting elements of the machine at the start by reducing the starting torque and efficiently protect the network from dangerous spikes through reduced power consumption. Through the continued Increase of the motor voltage, the network , the motor and load are optimally protected against voltage overload. The 3RW soft starters are small, inexpensive and can be easily combined with the SIRIUS contactors, power switches and overload relays.
