NS630bH — Schneider Electric ComPacT NS Large MCCB
The Schneider Electric ComPacT NS is a large molded case circuit breaker covering 630 A to 3200 A on supply voltages up to 690 V AC, designed for main incomer and bus section protection in large industrial and commercial LV switchboards where the current rating exceeds the NSX range and the full air circuit breaker format of the MasterPact MTZ is not required. The ComPacT NS occupies significantly less panel space and costs less than an ACB in the overlapping 630 A to 1600 A range, making it the optimum choice for main distribution panels in mid-size commercial buildings, sub-distribution boards in large industrial plants, and tie breaker applications in multi-source LV distribution systems.
The ComPacT NS uses the same Micrologic trip unit family as the NSX, offering Micrologic 2 through Micrologic 7 for the full spectrum from basic LSIG protection to advanced power quality measurement and earth fault monitoring. The Micrologic 5 trip unit provides class 0.5 energy metering accuracy, enabling the ComPacT NS to serve as the primary energy metering device for a distribution board without an external energy meter — satisfying SEC and utility billing metering accuracy requirements at transformer feeder level. The draw-out (withdrawable) version of the ComPacT NS enables racking out and insertion in the service position while the busbars remain energised, reducing planned maintenance duration for main incomer breakers in large commercial buildings.
In Saudi Arabia, the ComPacT NS KSA addresses the main incomer and principal sub-main circuit protection market for commercial buildings in the 630 A to 2000 A range. Large commercial towers in Riyadh and Jeddah with transformer ratings of 500 kVA to 2000 kVA use NS MCCBs as the main LV incomer protection device. Industrial facilities at Jubail and Yanbu use NS MCCBs as the main bus section breakers in process plant distribution boards. ROSHN large community centre and mixed-use development electrical rooms specify NS for transformer main incomer protection at the LV switchboard.
Razz Middle East stocks ComPacT NS in 630 A, 800 A, 1000 A, 1250 A, and 1600 A ratings with fixed and draw-out configurations and Micrologic trip unit options, for supply to switchboard manufacturers and project contractors across Saudi Arabia.

Key Features & Benefits
- 630 A to 3200 A current range covers transformer main incomer protection from 400 kVA to 2000 kVA at 400 V, bridging between the NSX range limit and the full ACB MasterPact format.
- Micrologic 5 class 0.5 energy metering accuracy satisfies SEC billing accuracy requirements for transformer feeder energy measurement, eliminating the need for a separate energy meter at the main incomer.
- Draw-out configuration with racking mechanism allows main incomer breaker removal and replacement with busbars energised, reducing planned maintenance shutdown duration for large commercial building electrical infrastructure.
- Same Micrologic trip unit family as ComPacT NSX enables consistent protection setting philosophy, training, and configuration tooling across the full NSX–NS product range in an organisation's distribution portfolio.
- Micrologic 6 differential earth fault protection detects low-level earth faults on large main distribution cables, providing fire prevention protection and early warning of insulation deterioration.
- Bus section and coupler breaker application capability in multi-source LV distribution systems allows the ComPacT NS to serve as the tie breaker between main and standby transformer incomers without ACB complexity.
- IEC 61439 certified panels from Saudi switchboard manufacturers using ComPacT NS receive full coordination documentation from Schneider Electric for project specification and SEC approval submissions.
Industrial Applications in Saudi Arabia
- Transformer main LV incomer protection in commercial tower electrical rooms across Riyadh, Jeddah, and Dammam, where 630–2000 A ratings cover the 500 kVA to 1600 kVA transformer ratings typical of high-rise commercial buildings.
- Industrial plant sub-distribution board main incomer protection at SABIC and ARAMCO contractor facilities, where draw-out capability enables planned maintenance without plant-wide power interruption.
- ROSHN community centre and mixed-use development transformer main incomer protection, where Micrologic 5 energy metering feeds data to EcoStruxure for community energy management reporting.
- Bus section breaker in multi-source LV distribution systems at hospitals and data centres requiring uninterruptible supply switching between normal and standby transformer sources.
- Large hotel main electrical room distribution protection in Makkah, Madinah, and Red Sea resort developments, where Micrologic 6 earth fault protection satisfies high-occupancy building fire prevention electrical requirements.
- SEC-approved panel builder LV switchboard assemblies for government and commercial infrastructure projects across Saudi Arabia, where IEC 60947-2 certified ComPacT NS is the standard large MCCB specification.
- Industrial facility main distribution panel incomer and bus section protection at MODON industrial city large-scale manufacturing tenant facilities, where 1600 A to 3200 A ratings cover large process plant power requirements.
