Termination is via screw terminals, which means a screwdriver and torque wrench for the power and control wiring — no spring-cage here, so budget time for proper torquing per the installation manual. ## Trip class and motor protection The trip class is selectable from Class 10A, 10E (default), 20E, or 30E per IEC 60947-4-2 — this lets you match the thermal overload curve to the motor's starting duty: Class 10 for standard starts, Class 20 or 30 for high-inertia loads like fans or crushers that need a longer ramp. Rated voltage spans 200 to 480 V AC, covering common global low-voltage motor supplies without a tap change. Service factor is 1.15, so the starter can handle a 15% continuous overload above the motor's nameplate rating — useful for intermittent overloads in pumping or conveying. ## Fieldbus and control integration On the control side, this unit supports Modbus RTU, Modbus TCP, and EtherNet/IP — three common industrial Ethernet and serial protocols — plus PROFIBUS if the application needs it. The analog output is configurable as 4-20 mA or 0-10 V, giving the PLC or SCADA a real-time motor current or torque signal without a separate transducer. Built-in torque control, breakaway pulse, and pump ramp down mean this starter handles demanding loads like high-friction conveyors or water hammer prevention without external add-ons. ## Compliance and approvals for global installs ATEX and IECEx certification (both marked Yes) mean this unit is approved for use in potentially explosive atmospheres — essential for oil & gas, chemical, or grain handling where the motor circuit must not become an ignition source. UL and CSA approval cover North American installations, while CE marking satisfies European Union directives — so this single order code works across most regulatory jurisdictions without a variant change.","metaTitle":"Siemens 3RW5558-6HA14 Soft Starter, 200-480V, ATEX, Active","metaDescription":"Siemens 3RW5558-6HA14 soft starter, 200-480V rated, ATEX certified, Class 10A/10E/20E/30E trip.
