WEG RW117 3-Pole Thermal Overload Relay — Class 10, Adjustable, for CWM95–CWM105 Contactors
The WEG RW117-1D3 is a 3-pole, Class 10 bi-metallic thermal overload relay that protects three-phase motors against overload and phase-failure conditions. It direct-mounts onto WEG CWM95–CWM105 contactors (or onto a separate base) to build a compact, reliable motor starter. Each version offers an adjustable current setting range, so you can dial in protection to match your motor's full-load amps.
