Trip class configurable as CLASS 10A, 10E (default), 20E, or 30E per IEC 60947-4-2, letting you match the thermal overload curve to the motor start profile — CLASS 10E for standard starts, CLASS 20E or 30E for high-inertia loads like crushers or centrifuges. ## ATEX and IECEx certification for hazardous areas ATEX and IECEx certified, meaning the soft starter is approved for use in potentially explosive atmospheres — a requirement for Zone 1 or Zone 2 gas environments and Zone 21 or Zone 22 dust environments, not just a general-purpose rating. ## Fieldbus connectivity and control features PROFIBUS and PROFINET support are available via optional communication modules, with PROFIenergy capability for energy management during idle phases. ## Motor protection and diagnostics depth Accuracy Class 5 per IEC 61557-12 means the current measurement error is within ±5 % — sufficient for motor protection without nuisance trips, and the basis for the event log and trace function that record start profiles and fault history. Service factor 1.15 allows continuous operation at 115 % of rated motor current without tripping, matching NEMA motor service factor ratings common in North American installations. ## Mounting dimensions and clearance requirements Height 306 mm, width 185 mm, depth 203 mm — the footprint fits standard 600 mm wide enclosures with room for side cabling. Required clearances: 100 mm above, 75 mm below, 10 mm in front, 5 mm at the sides, 0 mm behind the unit.","metaTitle":"Siemens 3RW5535-6HA16 Soft Starter, 200-690 V, ATEX, Active","metaDescription":"Siemens 3RW5535-6HA16 soft starter, rated 200-690 V, ATEX and IECEx certified, trip class 10A/10E/20E/30E.
