WEG Electric RW-E Series
Newest Additions!
- More WEG Electric RWB40E series electronic overload relays with remote reset function
WEG Electric RWB40E series solid state relays protect motors from thermal overloads in a wide range of industrial applications, including those with long starting times. These self-powered overload relays mount directly on WEG CWB/CWBN series contactors and protect motors in low-, medium-, or heavy-duty applications via DIP switch-adjustable trip class settings.
- Up to 40A FLA settings with wide adjustment ranges
- Selectable trip class (10, 20, or 30)
- Phase- loss protection (less than 5s)
- Phase imbalance protection (>40% between phases)
- Manual (local pushbutton on all models or remote 24 VDC input on select models) and automatic reset modes
- Thermal memory calculates motor heating and cooling to prevent premature automatic restarts after an overload trip
- 1N.O. + 1N.C. built-in auxiliary contacts for monitoring and control
