ريلاي قياس التيار ABB CME — نظرة عامة
ريلاي ABB CME هو ريلاي مراقبة DIN ريل مدمج يوفر حماية من الحمل الزائد والحمل الناقص وعدم تماثل الأطوار للمحركات ثلاثية الأطوار. يشغل وحدة 22.5 مم واحدة ويعمل بجهد من 24 فولت DC إلى 240 فولت AC.
يُستخدم معياراً للمراقبة على المحركات غير الحرجة في منشآت الطاقة والمياه والتكييف في المملكة العربية السعودية. توفر راز الشرق الأوسط عدادات CME من المخزون المحلي.

المميزات والفوائد
- Three-function protection in one 22.5 mm DIN module — overload, underload, and phase asymmetry — provides comprehensive current monitoring for non-critical motors without the cost of a full electronic motor protection relay.
- Universal 24–240 V AC/DC auxiliary supply voltage range simplifies panel design in mixed 24 V DC/230 V AC control systems, using the same relay without rewiring when supply voltage varies between panel types.
- Underload detection (set below normal running current) identifies pump dry-running, broken shaft, and lost-load conditions that cause motor overheating from reduced cooling airflow even at below-nameplate current levels.
- Phase asymmetry detection flags supply imbalance and developing winding faults before they cause a full phase failure, enabling planned motor maintenance rather than emergency breakdown response in continuous-process Saudi facilities.
- Adjustable trip delay from 0 to 30 seconds prevents nuisance trips during motor starting and load fluctuation transients, while still providing responsive protection against sustained overload conditions.
- LED front panel indication distinguishes operate status from fault type, allowing maintenance technicians to identify overload versus underload trip cause without additional diagnostic tools when investigating motor stops.
- SPDT output contact rated at 8 A, 250 V AC drives alarm annunciators, PLC digital inputs, contactor trip coils, and indicator lights directly without intermediate relay amplification, reducing component count in small to medium motor control panels.
التطبيقات الصناعية
- Cooling tower and condenser fan motor monitoring at commercial buildings across Riyadh and Jeddah, where underload detection catches fan blade loss or belt failure and overload detection flags bearing seizure before motor burnout.
- Domestic and booster water pump current monitoring in apartment towers and commercial buildings, where underload trip detects dry-running caused by inlet valve closure or water source depletion before pump seal failure occurs.
- Sump pump and drainage pump monitoring at road tunnels, underpasses, and building basement drainage systems, where underload detects pump-out-of-water condition and overload detects blockage before pump motor overheats.
- HVAC chiller auxiliary pump and fan monitoring at ARAMCO residential compound plant rooms, where the CME's three-in-one protection provides current monitoring across dozens of small auxiliary motors from a cost-effective DIN rail device.
- Conveyor and belt feeder current monitoring in food processing and packaging facilities, where overload detection flags material jam conditions for PLC interlock, preventing mechanical damage to the conveyor structure.
- Process agitator and mixer motor monitoring at chemical and pharmaceutical facilities in MODON industrial zones, where overload detects mixer blade contact with settled solids and underload detects broken agitator shaft or empty vessel.
- SEC substation cooling fan and battery room ventilation fan monitoring, where underload detection identifies fan belt failure or blade damage between periodic inspection visits, maintaining substation thermal management.
