Product description

The Siemens SIRIUS soft starter, part number 3RW4465-6BC34, is designed for smooth motor acceleration. At 460V and 50°C, it provides a standard current rating of 970 A and an inside-delta current rating of 1680 A. It operates on AC voltages from 200-460 V with a 115 V AC control voltage, featuring screw terminals. Please note that this product is phased out, with the SIRIUS 3RW5 series being its successor, specifically the 3RW5558-6HA14 as the preferred replacement.

This soft starter is intended for applications where controlled motor ramp-up is required to reduce mechanical stress and electrical current surges, such as in pump, fan, and conveyor systems. Its high current ratings make it suitable for large motor applications.
