Rated for 200-480 V supply, it covers the common industrial voltage range across Europe, Asia, and North America without needing a separate transformer tap. ## Fieldbus integration and control flexibility This soft starter supports PROFIBUS, Modbus RTU, Modbus TCP, and EtherNet/IP natively, so it drops into most common industrial networks without a separate gateway module. The analog output can be configured as 4-20 mA or 0-10 V, providing motor current or torque feedback directly to the PLC or drive controller for closed-loop monitoring. Built-in DC braking, voltage ramp, pump ramp down, torque control, and breakaway pulse give you application-specific starting and stopping profiles — pump ramp down prevents water hammer, breakaway pulse cracks high static friction loads. ## Safety functions and diagnostic depth One integrated fail-safe output provides a safe state with open load circuit, suitable for safety-related shutdowns in machinery guarding or process safety applications. The B10d value of 1,588,000 cycles supports reliability calculations for safety circuits per IEC 61508, useful when the soft starter is part of a safety function. Diagnostic tools include an event list, error logbook, and trace function — the trace captures motor current and voltage waveforms during starting events for troubleshooting intermittent faults. Motor heating protection with a service factor of 1.15 allows continuous operation at 115% of rated current without tripping, matching motor nameplate service factors common in pump and fan applications. ## Approvals and compliance documentation CE marking, UL approval, and CSA approval are listed, covering European and North American regulatory requirements for industrial control equipment. ATEX and IECEx certification are explicitly stated, so the unit is documented for installation in Zone 1 or Zone 2 gas atmospheres and Zone 21 or Zone 22 dust atmospheres — the specific gas group and temperature class should be verified against the installation certificate. Firmware update capability is supported, allowing field upgrades without replacing the hardware unit. ## Mounting dimensions and wiring The unit measures 170 mm wide, 275 mm high, and 152 mm deep — plan for a backpanel area roughly 170 x 275 mm plus clearance: 100 mm above, 75 mm below, 10 mm in front, 5 mm at the sides, and 0 mm behind. Power and control wiring uses solid conductors: two terminals accept 1.0-2.5 mm² and two accept 2.5-10 mm² — no screw terminals, so the connection type should be confirmed for the specific terminal design.","metaTitle":"Siemens 3RW5514-3HF04 Soft Starter, ATEX, 200-480V","metaDescription":"Siemens 3RW5514-3HF04 soft starter with ATEX & IECEx certification.
