NOARK Ex9N 3P 250A MCCB Thermal-Magnetic

The NOARK Ex9N 3P 250A Thermal-Magnetic Moulded Case Circuit Breaker (model 107006) is a frame-250 MCCB carrying the rare dual certification to both IEC 60947-2 and UL 489, providing a breaking capacity of 50 kA at 415 V AC — performance that positions it in direct competition with ABB Tmax T4 and Schneider ComPact NSX250F at a substantially more competitive mid-range price. Developed by NOARK's R&D engineers in Brno, Czech Republic, the Ex9N 250A addresses the protection tier where sub-main distribution feeders, large motor loads above 75 kW, and main incomer protection for secondary switchboards are required in Saudi Arabia's large commercial, industrial, and infrastructure projects. The adjustable thermal-magnetic trip unit covers the 160 A to 250 A current range with Ir adjustment, providing flexibility across the diverse load profiles encountered in Saudi industrial facilities without requiring a different frame size for each application.

The 50 kA breaking capacity of the Ex9N 250A brings it into the range required for main distribution boards served directly from medium-voltage/low-voltage transformers of 1,000 kVA and above — the transformer sizes commonly deployed in Saudi industrial parks, large commercial complexes, and ARAMCO and SABIC facility main substations. At these fault levels, the MCCB must reliably interrupt prospective fault currents that lower-rated devices cannot safely clear, making the 50 kA rating a genuine specification requirement rather than a marketing differentiator. The NOARK Ex9N 250A's Czech R&D design pedigree ensures the 50 kA test performance is achieved through genuine engineering rigour — including arc chamber geometry, contact material specification, and quenching splitter design — rather than through minimum-compliance testing, an important distinction for ARAMCO and SABIC procurement engineers who scrutinise technical data sheets carefully.

Saudi Arabia's large-scale industrial investment under Vision 2030 — including the Ras Al-Khair industrial complex, the Sudair Renewable Energy Zone electrical infrastructure, Qiddiya's 334 km² entertainment city main power distribution, and the extensive grid reinforcement works being executed by SEC across Riyadh, Jeddah, Mecca, and Medina in anticipation of 2030 population growth targets — creates consistent demand for 250 A frame MCCBs in both main distribution and motor feeder applications. The NOARK Ex9N 250A's dual IEC+UL certification makes it particularly valuable in joint-venture project procurement where the same EPC contractor must deliver both SEC-compliant main distribution panels and process equipment switchboards that reference NEC/UL standards. This dual-standard capability, combined with NOARK's Czech R&D positioning and Razz Middle East's local stock, creates a compelling value proposition for Saudi electrical contractors and panel builders managing multi-standard projects.

Razz Middle East maintains Ex9N 250A MCCB stock in Saudi Arabia with delivery capability to major industrial and commercial project sites within 48–72 hours. We provide comprehensive technical documentation in English and Arabic, including dual IEC and UL test certificates, SASO conformity declarations, and protection co-ordination data sheets. Our engineering team can conduct on-site MCCB commissioning, trip-unit setting optimisation, and annual maintenance testing for Ex9N MCCBs installed in Saudi industrial facilities, ensuring long-term reliable operation in the Kingdom's high-ambient-temperature environment.
