Description
The Schneider Electric EOCR-3DM2-WRDBWZ is a digital electronic motor protection relay with a 7-segment LED display and bar graph. It protects three-phase AC motors against overload, underload, locked rotor, phase loss, phase unbalance and phase reversal, with selectable definite, inverse and thermal trip curves. Motor leads pass through the built-in current windows, and the relay mounts on a 35 mm DIN rail or directly on a panel.
Protection Functions
- Overload (In > OC setting)
- Underload (In < UC setting)
- Locked rotor at start (2–8 × OC setting) and while running (1.5–5 × OC setting)
- Phase loss, phase reversal, phase unbalance (10–50%)
