Product details

Compliance and Certification Overview

The Siemens 3RW5526-1HA14 soft starter carries ATEX and IECEx certification for use in potentially explosive atmospheres, alongside UL, CSA, and CE marking — a fully documented compliance package for global installations. Rated voltage spans 200 to 480 V, covering common low-voltage motor networks worldwide. Trip class is selectable among CLASS 10A, 10E (default), 20E, or 30E per IEC 60947-4-2, giving the commissioning engineer flexibility to match motor thermal characteristics without changing hardware.

Dimensions are 185 mm wide, 306 mm high, and 203 mm deep, with required clearances: 100 mm upward, 75 mm downward, 10 mm forward, 5 mm at the side, and 0 mm backward — panel layout must respect these for adequate ventilation and access. Screw terminals are standard; no special tooling required for wiring.

Functional Capabilities

Built-in features include voltage ramp start, torque control, breakaway pulse, pump ramp down, DC braking, and motor heating — covering soft starting, stopping, and protection for a wide range of motor-driven loads. Communication options include PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET with PROFIenergy support, plus an analog output configurable for 4-20 mA or 0-10 V. Diagnostic capabilities include an event list, error logbook, trace function, and remote reset — useful for fault isolation and remote troubleshooting. Accuracy Class 5 per IEC 61557-12 applies to the measurement functions, and a service factor of 1.15 is supported for overload settings.
