NewTrend / OEM · EOCR-3DE/3EZ
Product overview
NewTrend/OEM EOCR-3DE and EOCR-3EZ monitor three-phase motor current through integral current transformers. The 3DE includes a load-alert output; the 3EZ version adds ground-fault protection.
Technical selection summary
| Direct current range | 0.5–60A with one conductor pass; 0.25–30A with two passes; 0.1–12A with five passes, per original CT table |
|---|---|
| External CT | 1–960A overall through exact 10:5 to 800:5 CT rows. Select the matching CT ratio and range from the retained native table; an external CT is not assumed included |
| Control supply | 24VAC/DC, 110VAC ±15%, or 220VAC ±15%; AC 50/60Hz |
| Outputs | 3DE: OL 1NO+1NC and AL 1NO. 3EZ: OL 1NO and GR 1NO. Contact rating 3A at 250VAC resistive |
| Protection | Overcurrent, undercurrent, phase loss, unbalance, reversal and locked rotor; ground fault only on 3EZ |
| Timing | D-TIME 1–200s; inverse O-TIME 1–30; definite O-TIME 0.2–30s, as labelled in the original reference |
| Installation / wiring | 35mm DIN rail; retain separate 3DE and 3EZ wiring diagrams. This OEM product is not represented as original Samwha/Schneider |
Provide motor current, supply, selected version, CT ratio if required and quantity. Confirm the exact delivered suffix and wiring before installation.
Typical applications
- Motor overcurrent and phase-fault monitoring
