وحدة مراقبة التيار المتبقي سيمنز 5SM3 — نظرة عامة
وحدة مراقبة التيار المتبقي 5SM3 من سيمنز تقيس تيارات التسرب الأرضي بشكل مستمر من 3 مللي أمبير إلى 1 أمبير بعتبتي إنذار قابلتين للضبط بدون قطع الدائرة، مع خيار Modbus RTU للتكامل مع أنظمة BMS وإدارة الطاقة.
تُستخدم في المستشفيات ومراكز البيانات والمنشآت البتروكيماوية في المملكة العربية السعودية حيث تستلزم استمرارية الدائرة مراقبة العزل بدلاً من القطع. توفر راز الشرق الأوسط 5SM3 مع دعم هندسة مراقبة العزل الطبية والصناعية.

المميزات والفوائد
- Continuous leakage current measurement without circuit interruption enables earth fault monitoring in applications where circuit trips cause unacceptable operational impact — operating theatres, ICU areas, data centre critical feeds, and continuous process control circuits.
- Two independently adjustable alarm thresholds — pre-alarm for maintenance scheduling and high-alarm for immediate investigation — implement a two-stage response protocol that distinguishes gradual degradation from acute faults.
- Measurement range from 3 mA enables high-sensitivity medical location monitoring per IEC 60364-7-710 Group 2 requirements, covering both body-protection-level and equipment-protection-level earth fault detection from a single device.
- RS-485 Modbus RTU communication option provides real-time leakage current readings to BMS and energy management systems, enabling centralised trending and predictive maintenance scheduling across large multi-circuit installations.
- Leakage current trending on the Modbus output reveals gradual insulation degradation months before complete failure, providing advance warning that eliminates unplanned circuit outages at critical Saudi facilities.
- External toroidal CT measurement technique allows the 5SM3 to monitor circuits of any current rating without a current rating change to the monitor itself, covering both small final circuits (10–32 A) and large distribution feeders (100–800 A).
- DIN-rail mounting in standard 72 mm width integrates the 5SM3 into any distribution board or control panel alongside MCBs, RCCBs, and MCCBs without additional enclosure hardware.
التطبيقات الصناعية
- Group 2 medical location earth fault monitoring at Saudi hospitals and healthcare facilities including King Salman and King Faisal Specialist Hospitals, where IEC 60364-7-710 requires continuous insulation monitoring on operating theatre and ICU power circuits.
- Data centre critical circuit earth fault monitoring at National Data Centre and hyperscale cloud facilities in Riyadh, where 5SM3 monitors UPS output and PDU distribution circuits for early insulation degradation without tripping critical IT loads.
- Ungrounded IT system distribution monitoring at ARAMCO and SABIC classified areas, where IECEx-compliant IT earth monitoring with continuous ground fault tracking maintains intrinsically safe circuit integrity without supply interruption.
- NEOM hospital and research campus critical circuit monitoring, where 5SM3 modules provide the insulation monitoring layer for all Group 2 medical location and critical life-safety circuit distributions from the outset.
- Pharmaceutical manufacturing clean room circuit monitoring at Vision 2030 healthcare manufacturing facilities, where 5SM3 trending enables predictive maintenance of critical environmental control circuits without cleanroom contamination risk.
- Airport and transport infrastructure critical power circuit monitoring at King Abdulaziz International Airport expansions and NEOM's air mobility infrastructure, where continuous earth fault monitoring meets CAA electrical installation requirements for aviation-critical power supplies.
- High-rise commercial tower and hotel critical circuit monitoring in Riyadh's King Abdullah Financial District and Jeddah's Corniche developments, where BMS-integrated 5SM3 Modbus data provides centralised insulation health monitoring for facility management teams.
