WEG RW67-5D2 2-Pole Thermal Overload Relay — Class 10, for CWB40–CWB80 Contactors
The WEG RW67-5D2 is a 2-pole bi-metallic thermal overload relay sized for larger motor circuits, protecting against overload, phase loss, and current imbalance. It mounts directly onto WEG CWB40 through CWB80 IEC contactors (40–80 A frame) or can be panel-mounted with a separate-mounting kit. Each model covers a specific, infinitely adjustable trip-current band — choose the band that brackets your motor's full-load amps (FLA).
Key specifications

Typical applications
Used in motor-starter and control-panel builds for larger pumps, fans, compressors, conveyors, and general-purpose AC motors where reliable overload and single-phasing protection is required.
Pair the WEG RW67-5D2 Class 10 thermal overload relay with a matching WEG CWB40–CWB80 contactor to build a robust, code-compliant motor starter. Select the setting range that matches your motor's full-load current for accurate, dependable overload protection.
