WEG RWM40E-3-R4U040 Electronic Overload Relay 8.00-40.0 Amp Remote Reset

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.

This model features 2 extra control terminals, A3,A4, for optional remote reset. By applying 24VDC to these terminals, the relay may be reset from an overload condition. Manual reset still available from the blue button on the front.
