WEG RW67-5D2-U063 Adjustable Thermal Overload Relay

The WEG RW67-5D2-U063 adjustable thermal overload relay is a 2-pole, 50–63 A device designed for direct mounting on WEG CWM contactors to deliver reliable motor overload and phase loss protection for three-phase motors in industrial motor control systems. It provides Bi-Metallic thermal overload protection plus phase loss and current unbalance protection, with a Class 10 trip and an adjustable current range that covers a range of motor sizes. Commonly installed in manufacturing facilities, conveyor systems, pumping stations, HVAC equipment, and automation panels, the RW67-5D2-U063 supports motor starters and automation equipment requiring continuous-duty operation and dependable protection. Key specs include a 690 V rated insulation voltage, 6 kV rated impulse withstand voltage, and a 25–400 Hz rated operational frequency, along with an auxiliary contact set of 1 NO + 1 NC. The unit offers IP20 protection on the auxiliary terminals and IP10 on the main terminals, a reset that can be manual or automatic, and compatibility with WEG CWM contactors for direct mounting in motor control centers and automation panels. Common replacements include Allen-Bradley E100, Siemens Sirius, and Schneider Electric TeSys overload relays.
