Rated 200 … 480 V, it covers the common European and North American motor voltages without a transformer tap change. Trip class is configurable between CLASS 10A / 10E (default), 20E, and 30E per IEC 60947-4-2, so you can match the thermal curve to the motor's starting profile — CLASS 10 for standard induction motors, CLASS 20 or 30 for high-inertia loads like centrifuges or crushers that need a longer ramp. ## Fieldbus and safety integration This soft starter ships with PROFIBUS, Modbus RTU, Modbus TCP, and EtherNet/IP onboard — no separate communication module to order, which saves a slot and a line item. PROFIenergy is supported when paired with a PROFINET communication module. The fail-safe input (1 safe channel) puts the output in a defined safe state — open load circuit — so a safety PLC or safety relay can drop the starter independently of the main control loop. That matters for zones where a guard-door interlock must kill motor torque before an operator can reach in. Remote reset and auto-reset are both available, which lets a control system re-start the motor after a fault without a panel walk — useful for remote pump stations or conveyor lines. At 306 mm high × 185 mm wide × 203 mm deep, this is a full-frame SIRIUS soft starter — not a compact. Clearance requirements: 100 mm above, 75 mm below, 5 mm at the sides, 10 mm in front, 0 mm behind. The zero rear clearance means it can sit flush against a back panel or gland plate, which helps when you are squeezing a starter into a crowded enclosure. Screw terminals are standard — no spring-cage option on this variant. For a panel builder that means consistent torque values across all power and control connections. ## Motor protection and diagnostics Motor heating model, torque control, voltage ramp, pump ramp down, and breakaway pulse are all built in. The analog output can be configured for 4 … 20 mA or 0 … 10 V to feed a PLC or local indicator with motor current or torque feedback. Accuracy Class 5 per IEC 61557-12 means the current measurement is within 5 % — adequate for overload protection and basic energy monitoring, not for billing-grade metering. The event list, error logbook, and trace function give a technician the sequence of faults leading up to a trip without needing a separate data logger. DC braking is included, which can stop a motor faster than coasting on applications like conveyors or saws where a quick stop reduces mechanical wear. The part carries CE, UL, and CSA approvals, which means it is accepted in European and North American markets without additional certification work. The B10d value of 500 000 cycles provides a reliability benchmark for safety-function planning.","metaTitle":"Siemens 3RW5534-6HF14 SIRIUS Soft Starter, ATEX, 200-480V","metaDescription":"Siemens 3RW5534-6HF14 SIRIUS soft starter with ATEX & IECEx certification for hazardous locations.
