WEG RW67-2D3-U070 Three-Phase Adjustable Overload Relay

The WEG RW67-2D3-U070 three-phase adjustable overload relay directly mounts to WEG CWM contactors to deliver precise motor overload and phase‑failure protection in industrial motor control. Its adjustable current range is 57–70 A across 3 poles, with bi-metallic thermal protection and a Class 10 trip, plus phase protection for phase loss and current unbalance. The unit includes one normally open + one normally closed isolated auxiliary contact, a manual/automatic reset selectable, rated insulation voltage 690 V, 6 kV rated impulse withstand, and a rated operational frequency of 25–400 Hz, with IP20 protection on auxiliary terminals and IP10 on main terminals. This assembly is designed for direct mounting and is compatible with WEG CWM contactors, making it suitable for motor starters in conveyors, pumps, compressors, HVAC, and other automation equipment; common replacements include Allen-Bradley E100, Siemens Sirius, and Schneider Electric TeSys overload relays.
