The insulation voltage is rated 690 V, operating frequency 50/60 Hz, and it supports inside-delta wiring for reduced line current on delta-connected motors. ## Mounting and wiring constraints for the panel Mounting is by screw fixing; the unit accepts vertical mounting surfaces with +/-90° rotation and +/-22.5° tilt front-to-back. Dimensions are 270 mm deep, 170 mm wide, 200 mm high — plan the enclosure depth accordingly. Clearance requirements: 100 mm above, 75 mm below, 5 mm at the sides for airflow. Sourced through authorized distribution channels; quantities are quoted against the BOM with lead time and pricing confirmed at RFQ.","metaTitle":"Siemens 3RW4434-6BC46 SIRIUS Soft Starter, 196 A at 40 °C","metaDescription":"Siemens SIRIUS 3RW4434-6BC46 soft starter, 196 A at 40 °C, 690 V insulation, thyristor-based, active production.
