Ex-rated soft starter for hazardous-area motor control
The 3RW5076-6TB05: This means it can be installed in Zone 1 or Zone 2 gas atmospheres and Zone 21 or Zone 22 dust atmospheres per IEC 60079, making it suitable for offshore platforms, chemical plants, and grain-handling facilities where a standard soft starter would fail the loop-check. Minimum rated current is 200 A across a 200-600 V supply range. The trip class is configurable as CLASS 10A, 10E, or 20E per IEC 60947-4-2, which governs the allowable overload protection time — CLASS 10E matches standard motor thermal curves for pumps and fans, while CLASS 20E gives extra headroom for high-inertia loads like centrifuges.
Fieldbus integration and control flexibility
This unit supports PROFIBUS, Modbus RTU, Modbus TCP, EtherNet/IP, and PROFINET standard — no separate communication module required for most networks. The PROFINET variant also enables PROFIenergy for coordinated energy management during production pauses. Mounting position allows vertical surface installation with ±90° rotation and ±22.5° tilt forward/back. Screw fixing is the fastening method — no DIN-rail clip, so panel cutouts must be planned for bolt-down. Dimensions are 282 mm depth, 160 mm width, 230 mm height; the 100 mm upward clearance and 75 mm downward clearance must be respected for airflow.
Active lifecycle and sourcing posture
Approvals include UL, CSA, and CE marking — covering North American and European regulatory jurisdictions without additional certification effort.
