المميزات والفوائد
- Compact footprint — the 630 A NSX630 occupies less space than many competing 400 A MCCBs — enabling significant distribution board size reduction and cost saving in LV switchboard assemblies.
- Micrologic trip unit progression from basic LSIG to energy metering to power quality measurement allows the same NSX frame to serve simple protection or advanced energy management requirements without frame change.
- Selective coordination with downstream Acti9 MCBs at 10 ms trip time ensures fault discrimination, maintaining supply to all healthy circuits when a fault occurs on one branch without tripping the upstream NSX.
- Draw-out (withdrawable) version with racking mechanism enables MCCB replacement and maintenance in the service position without de-energising the main busbar, reducing planned maintenance downtime.
- Modbus RTU and TCP communication via Micrologic 5 and higher trip units provides energy consumption, demand, and fault history data to building energy management and SCADA systems.
- Differential earth fault protection in Micrologic 6 detects low-level earth faults not detected by conventional LSIG protection, providing fire prevention-level protection on large cable circuits in commercial buildings.
- IEC 60947-2 short-circuit performance with current limitation on magnetic trip reduces energy let-through and peak fault force on downstream wiring, protecting cables and busbars from the mechanical effects of high fault current.
التطبيقات الصناعية
- Sub-main distribution protection in IEC 61439-compliant LV switchboards assembled by SEC-approved panel builders for commercial tower, government building, and infrastructure projects across Saudi Arabia.
- Motor feeder circuit breakers in ARAMCO and SABIC motor control centres, where NSX with Micrologic trip unit provides motor overload and short-circuit protection with Modbus data to the plant DCS.
- Main incomer and sub-main breakers in NEOM smart city LV distribution panels, where Micrologic 5 energy metering feeds data to EcoStruxure for real-time energy consumption monitoring across the smart city grid.
- Industrial distribution panel branch circuit protection at MODON industrial estate tenant factories, where draw-out capability enables MCCB replacement during production without de-energising the main distribution busbar.
- Red Sea Project resort electrical infrastructure sub-main distribution, where ComPacT NSX's compact footprint reduces distribution switchboard size in the constrained plant room layouts of luxury resort architecture.
- Healthcare facility main distribution MCCBs in Ministry of Health hospital projects, where Micrologic earth fault protection and selective coordination satisfy hospital electrical installation safety standards.
- Data centre UPS bypass and distribution switchboard MCCBs in Riyadh and Jeddah hyperscale facilities, where draw-out capability enables live maintenance without data centre power interruption.
