Rated voltage is 200-480 V, covering the common low-voltage motor systems across 50 Hz and 60 Hz regions; the control supply accepts 110-250 V at either frequency. Trip class is selectable between CLASS 10A (default), CLASS 10E, CLASS 20E, and CLASS 30E per IEC 60947-4-2 — this lets the commissioning engineer match the thermal overload curve to the motor's winding time constant, avoiding nuisance trips on high-inertia starts while still protecting against locked-rotor conditions. ## Fieldbus integration and analog feedback Onboard communication includes Modbus RTU, Modbus TCP, and EtherNet/IP — the soft starter connects directly to a PLC backplane without a separate gateway module, saving a DIN-rail slot and reducing IP address consumption. An analog output configurable as 4-20 mA or 0-10 V provides real-time motor current to a SCADA system or local panel meter, enabling trending of start-up current profiles for predictive maintenance. PROFIBUS and PROFIenergy are supported when paired with the PROFINET communication module, allowing energy monitoring and coordinated shutdown sequences in automated lines. ## Advanced starting and stopping profiles Voltage ramp provides the basic soft-start profile; torque control adds a current-limited acceleration phase for loads that need a constant torque ramp rather than a voltage ramp — relevant for screw compressors and extruders where the load torque increases with speed. Breakaway pulse delivers a short high-torque burst to break static friction before the ramp begins — useful on belt conveyors and positive-displacement pumps that have a high breakaway torque requirement. Pump ramp down decelerates the motor gradually on stop, reducing water hammer in pumping systems; DC braking provides controlled deceleration for high-friction loads without mechanical brake wear. ## Panel integration and clearance requirements Physical dimensions are 306 mm height, 185 mm width, 203 mm depth — this is a panel-mount unit that requires 100 mm clearance above, 75 mm below, 10 mm in front, 5 mm at the sides, and 0 mm behind for airflow and wiring access. Termination is via screw-type terminals (: No indicates spring-clamp or ring-lug connection — confirm the exact termination style from the installation manual before panel layout). Accuracy class 5 per IEC 61557-12 applies to the integrated current measurement; service factor 1.15 means the soft starter can sustain 115% of rated current continuously without derating — relevant for applications where the motor runs near full load. The safe state is open load circuit, meaning the fail-safe output (: 1 channel) opens the motor circuit on a fault condition, ensuring the motor stops even if the control system loses power.","metaTitle":"Siemens 3RW5534-2HF14 Soft Starter, 200-480V, ATEX","metaDescription":"Siemens 3RW5534-2HF14 soft starter, rated 200-480 V, ATEX certified, trip class CLASS 10A/10E/20E/30E per IEC 60947-4-2.
