230 V control unit for 3RW4076 — what it replaces on the panel
The Siemens 3RW4776-6SB40 is a control unit for the 3RW4076 soft starter, Size S12, with screw terminals and a 230 V supply. It is the brain that handles the start/stop logic, ramp timing, and fault monitoring for the power module — without it the soft starter stack won't sequence.
