WEG WEG RWM420E-3-A4U250 Electronic Overload Relay 50.0-250 Amp
The Weg RW-E series of electronic overload relays are designed to protect expensive motors from damage due to overloads, phase loss, and current unblances. The Weg electronic relay is up to 87% more energy efficient compared to thermal overload relays, saving on both energy and cabinet ventilation demands. They also have a much larger settable current range as compared to the thermal overloads, thus reducing spare parts inventory. The entire current range from 0.4 to 820 amps is covered by just 4 RW-E products.
