WEG RW67-5D2-U040 Adjustable Overload Relay for CWB Contactor

The WEG RW67-5D2-U040 adjustable overload relay is used in industrial motor control and automation systems to provide thermal overload and phase failure protection for three-phase motors and contactor assemblies, and it mounts directly to compatible WEG CWM contactors. This 2-pole device features a 25–40 A adjustable current range, bi-metallic thermal overload protection, a Class 10 trip, and a 690 V rated insulation voltage with a 6 kV rated impulse withstand. It includes 1 normally open and 1 normally closed isolated auxiliary contact, a manual/automatic selectable reset, and phase protection for phase loss and current unbalance across a frequency range of 25–400 Hz. Designed for direct mounting as an industrial thermal overload relay assembly, the RW67-5D2-U040 is compatible with WEG CWM contactors and suitable for motor control centers and automation panels in pumps, fans, compressors, conveyors, HVAC equipment, and other industrial machinery. Common replacements for this model include Allen-Bradley E100, Siemens Sirius, and Schneider Electric TeSys overload relays.
