Starting profiles include voltage ramp, torque control, pump ramp down, breakaway pulse, and DC braking — covers soft start, controlled stop, and jogging. ## Fieldbus and control integration Supports PROFIBUS, Modbus RTU, Modbus TCP, and EtherNet/IP — drops into existing control networks without a separate gateway module. Analog output configurable as 4-20 mA or 0-10 V for motor current or torque feedback to the PLC or drive controller. Event list, error logbook, and trace function built in — useful for commissioning and fault analysis without external software. ## Approvals and compliance CE marked, UL and CSA approved — accepted in North American and European installations without additional agency review. ATEX and IECEx certification (Yes) means this unit can start motors in Zone 1 or Zone 2 classified areas when properly installed with the matching motor and cabling. ## Panel mounting and clearances Dimensions are 306 mm height, 185 mm width, 203 mm depth — fits standard 600 mm deep enclosures with room for wiring ducts. Minimum clearance requirements: 100 mm above, 75 mm below, 5 mm sides, 10 mm front, 0 mm rear — plan the panel layout accordingly for airflow and heat dissipation.","metaTitle":"Siemens 3RW5526-3HF14 Soft Starter, 200-480 V, ATEX","metaDescription":"Siemens 3RW5526-3HF14 soft starter, rated 200-480 V, ATEX/IECEx certified, configurable trip class, multi-protocol fieldbus.
