WEG RW67-1D3-U040 Industrial Adjustable Overload Relay

The WEG RW67-1D2-U040 industrial adjustable overload relay delivers reliable motor protection for 3‑phase systems by combining bi-metallic thermal overload with phase loss and current unbalance protection. Designed for direct mounting on WEG CWM contactors, this 3-pole device offers an adjustable current range of 25–40 A and a Class 10 trip rating, ensuring timely shutdown during overload while allowing continuous operation in normal conditions. It includes 1 normally open and 1 normally closed auxiliary contact, with a manual/automatic reset selectable, and supports voltages up to 690 V and a rated impulse withstand of 6 kV. The relay operates across 25–400 Hz and is built for industrial duty in pumps, fans, compressors, conveyors, and other automation equipment, with IP20 protection on the auxiliary circuit and IP10 on main terminals. Compatible installations include motor control centers and automation panels, making it suitable for motor starters and other industrial machinery to ensure dependable motor overload protection and phase failure detection.
