Form factor and mounting — panel fit for a 306 x 185 x 203 mm frame
The 3RW5234-6TC05 measures 306 mm high by 185 mm wide by 203 mm deep, screw-fixed to a vertical mounting surface with ±90° rotation and ±22.5° tilt front-to-back allowed. Clearance requirements: 100 mm above, 75 mm below, 10 mm forward, 5 mm sideways, zero backward — plan the gland plate and busbar routing accordingly.
Trip class and motor protection — Class 10A default, 10E and 20E selectable
Default trip class is 10A per IEC 60947-4-2, with selectable 10E and 20E for higher-inertia loads like centrifuges or crushers. The minimum settable current is 53 A, with a 15 % minimum load relative to that Ie — so the soft starter handles motors down to about 8 A if the BOM calls for a wide current range.
Fieldbus connectivity — PROFIBUS, Modbus RTU/TCP, EtherNet/IP, PROFINET
Onboard PROFIBUS and Modbus RTU, plus Modbus TCP, EtherNet/IP, and PROFINET standard — no separate communication module needed for most plant networks. PROFIenergy is supported via the PROFINET interface, useful for coordinated energy management during idle phases.
Operating temperature and derating — -25 to +60 °C, derate above 40 °C
Rated for -25 to +60 °C during operation, but Siemens explicitly notes derating at 40 °C or above — size the enclosure ventilation and check the ambient against the load profile if the panel sits near a heat source. Pollution degree 3 per IEC 60947-4-2 means the unit tolerates conductive dust and humidity typical of industrial floors.
Pump and soft-torque features — pump ramp down, soft torque, auto-reset
Includes pump ramp down to avoid water hammer on stop, and soft torque for gentle acceleration of conveyors or fans. Auto-reset is standard; remote reset is possible by cycling the 24 V control supply. The error logbook is accessible with the optional accessory — useful for fault analysis during commissioning.
Approvals and compliance — UL, CSA, CE, shock resistance 15 g
UL and CSA approved, CE marked — covers North American and European installations. Shock resistance is 15 g / 11 ms, with potential contact lifting noted at 12 g / 11 ms; the unit holds the line under moderate vibration but should not be mounted directly on a reciprocating compressor frame without isolation.
