It supplies the logic and gate-drive signals at 230 V, with screw terminals for field wiring. This is the brain of the soft starter assembly; the power section (thyristors, bypass contactor) lives in the 3RW4426 frame. The control unit handles start/stop sequencing, ramp profiles, and motor protection parameters. ## Lifecycle status and compliance baseline RoHS compliance is confirmed per the substance prohibitance date of 07/01/2006. The part meets the EU RoHS directive effective from that date, covering lead, mercury, cadmium, and the other restricted substances. ## Sourcing posture for this control unit If the 3RW4726-1SC44 is the specified control unit for your 3RW4426 soft starter, the replacement path is the same order code.","metaTitle":"Siemens 3RW4726-1SC44 Soft Starter Control Unit, 230 V","metaDescription":"Siemens 3RW4726-1SC44 control unit for 3RW4426 soft starter, 230 V, screw terminals.
