Product details

Soft starter for ATEX-rated motor circuits

The Siemens 3RW5517-3HA04 is a soft starter with ATEX certification (Yes) and IECEx (Yes), making it suitable for starting motors in potentially explosive atmospheres where controlled acceleration and deceleration are required per the equipment protection level. Rated voltage is 200-480 V, covering common low-voltage motor supplies across 50/60 Hz networks worldwide. The trip class is configurable between CLASS 10A / 10E (default) / 20E / 30E per IEC 60947-4-2, allowing coordination with motor thermal protection for normal-start, heavy-start, or extended-start duty cycles. Global approvals include UL (Yes), CSA (Yes), and CE marking (Yes), satisfying North American and European regulatory requirements for panel builders and site electrical engineers.

Panel integration and mounting clearances

Dimensions are 170 mm width, 275 mm height, and 152 mm depth, fitting standard enclosure backplate layouts. Required clearances: 100 mm upwards, 10 mm forwards, 0 mm backwards, 75 mm downwards, and 5 mm at the side — these must be maintained for airflow and thermal dissipation. Solid connections accept 2x (1.0-2.5 mm²) and 2x (2.5-10 mm²) conductors; screw terminals are not used (No), so the wiring method is likely spring-cage or push-in — confirm the termination type on the product drawing before panel wiring.

Fieldbus and control integration

Supports PROFIBUS (Yes), Modbus RTU (Yes), Modbus TCP (Yes), and EtherNet/IP (Yes), covering the three dominant industrial Ethernet protocols plus legacy PROFIBUS. PROFIenergy is supported in connection with PROFINET Standard and PROFINET High-Feature communication modules, enabling energy management during idle phases. The accuracy class is 5 per IEC 61557-12, suitable for monitoring rather than precision metering.

Motor control features for demanding applications

Includes voltage ramp (Yes), torque control (Yes), pump ramp down (Yes), breakaway pulse (Yes), and DC braking (Yes) — these cover soft starting, soft stopping, and braking for pumps, conveyors, fans, and high-inertia loads. Combined braking (Yes) integrates DC injection with the ramp profile for faster controlled stops. Auto-reset (Yes) and remote reset (Yes) allow automated restart after a fault trip, reducing manual intervention in remote or unmanned installations. Motor heating (Yes) provides pre-heating for motors in cold environments to prevent condensation or winding damage before start. Diagnostic features include an event list (Yes), error logbook (Yes), and trace function (Yes) for post-fault analysis. Firmware update (Yes) allows field upgrades without replacing the unit.

Frequently asked questions

What compliance documentation does Siemens provide for 3RW5517-3HA04?

The soft starter carries UL approval (Yes), CSA approval (Yes), and CE marking (Yes), covering North American and European regulatory requirements. ATEX (Yes) and IECEx (Yes) certifications are also listed for hazardous-area installations. RoHS and REACH documentation is typically provided by Siemens upon request.
