Product details

Active production, fieldbus-ready motor starting

The Siemens 3RW5075-2TB15 is a current-production soft starter rated for a minimum 160 A at 200-600 V, designed for three-phase induction motor starting with a preset Class 10A or selectable 10E/20E trip profile per IEC 60947-4-2. It carries onboard PROFIBUS, Modbus RTU, Modbus TCP, and EtherNet/IP interfaces, so it drops into a PLC-controlled line without a separate gateway module.

Trip class and motor protection

The 10E and 20E settings extend the ramp time for higher-inertia loads like centrifuges or crushers. The minimum load setting is 15 % of the smallest settable Ie, so it can start lightly loaded conveyors or pumps without nuisance tripping.

Compliance and approvals for hazardous areas

ATEX and IECEx certified, plus CE, UL, and CSA marks — this unit is panel-ready for Zone 2 / Zone 22 installations and North American 600 V class systems.

Mounting and panel integration

Screw-fixed mounting, 160 mm wide × 230 mm tall × 282 mm deep. Clearance requirements: 100 mm upward, 75 mm downward, 10 mm forward, 5 mm sideways — plan the enclosure depth and cable duct accordingly. Mounting position is vertical, rotatable ±90° or tiltable ±22.5° front-to-back, which gives flexibility in tight retrofit panels.
