The screw-fixing fastening method means it bolts directly to the backplate, not a snap-on rail, so the mounting holes must be laid out before the panel is punched. Clearance requirements are tight: 100 mm above, 75 mm below, 10 mm forward, and 5 mm at the sides. No clearance is needed behind the unit. This asymmetry matters when stacking multiple soft starters in a row — the vertical gaps eat into the usable panel height faster than the horizontal ones. Mounting position is forgiving: the unit accepts a vertical mounting surface with ±90° rotation and ±22.5° tilt forward or backward. That lets you angle it away from a hot busbar or toward a cooling duct without a custom bracket. ## Rated current floor and trip class — what drives the motor protection Minimum rated current is 81 A. That is the floor for the smallest settable motor full-load current (Ie) the soft starter can protect — anything below 81 A and the internal overload curve cannot be calibrated low enough. For a 50 hp motor at 460 V (roughly 65 A FLA), this starter is oversized; you would need a lower-rated unit in the same SIRIUS family. Trip class defaults to CLASS 10A, with selectable CLASS 10E and CLASS 20E per IEC 60947-4-2. The 200-480 V rated voltage range covers 208 V, 240 V, 277 V, 400 V, and 480 V line supplies — common across North American and European industrial panels. No 575 V or 600 V coverage here; those need the higher-voltage variant in the series. ## Fieldbus suite for the controls layer This soft starter carries PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET. That is a full industrial Ethernet and fieldbus portfolio — no gateway needed for most PLC racks. PROFIenergy is supported via the PROFINET standard communication module, letting the drive coordinate energy-saving idle states with the rest of the line. The 24 V DC control supply powers the electronics and the communication module; it is separate from the motor power circuit, so the bus stays alive even when the main contactor is open. Remote reset is available by cycling the control supply voltage — useful for unattended restart after a fault. ## Active lifecycle and regulatory acceptance CE marking, UL approval, and CSA approval are all confirmed. That covers the three major industrial certification regimes: European CE for the Machinery Directive, UL for US panel acceptance, and CSA for Canadian installations. Pollution degree 3 per IEC 60947-4-2 means it is rated for conductive pollution in industrial atmospheres — no special enclosure needed for most factory floors. ## Thermal limits and shock tolerance in a mill environment In a steel mill where the cabinet near the rolls can hit 50 °C, you must derate the continuous output current per the curve in the manual — the nameplate rating applies only up to 40 °C. This unit takes the radiant heat better than a commercial-temp drive, but the derating is real and must be calculated. Shock resistance is 15 g for 11 ms, dropping to 12 g for 11 ms if potential contact lifting is a concern. That is robust enough for a vibrating conveyor line or a crusher feeder, but a direct hit from a drop hammer or a press might exceed the rating — mount it on a vibration-dampening bracket if the shock source is within a few meters.","metaTitle":"Siemens 3RW5236-6TC04 Soft Starter, 81 A min, 200-480 V","metaDescription":"Siemens 3RW5236-6TC04 SIRIUS soft starter, 81 A minimum rated current, 200-480 V, CLASS 10A/10E/20E trip, PROFIBUS/Modbus/EtherNet/IP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Soft Starters"],"specifications":{"Depth":"203 mm","Width":"185 mm","title":"3RW5236-6TC04","Height":"306 mm","Minimum":"81 A","Upwards":"100 mm","Forwards":"10 mm","PROFIBUS":"Yes","Backwards":"0 mm","Downwards":"75 mm","CE marking":"Yes","Modbus RTU":"Yes","Modbus TCP":"Yes","Trip Class":"CLASS 10A (default) / 10E / 20E;
