It runs on 115 V AC and connects via screw terminals, so no special tooling needed for the panel wiring. ## Lifecycle and supply reality Substance Prohibitance date of 01.05.2012 references the RoHS compliance cutoff — the part meets EU RoHS requirements for lead, mercury, cadmium, and the other restricted substances. ## Panel fit and wiring Screw terminals on a control unit mean you land the 115 V control power with a standard slotted driver — no push-in or spring-cage tool needed. The unit mounts into the 3RW4074 Size S12 soft starter frame, which itself sits on a DIN rail or panel. The Product Designation is Control unit — it's not the power module. You pair this with the 3RW4074 power section; the control unit alone doesn't switch motor current.","metaTitle":"Siemens 3RW4774-6SB30 Soft Starter Control Unit, 115 V","metaDescription":"Siemens 3RW4774-6SB30 control unit for 3RW4074 Size S12 soft starter, 115 V coil, screw terminals.
