NOARK Ex9N 3P 100A MCCB Thermal-Magnetic

The NOARK Ex9N 3P 100A Thermal-Magnetic Moulded Case Circuit Breaker (model 107003) is a compact frame-160 MCCB carrying a dual certification to both IEC 60947-2 and UL 489 — a combination that is rare among mid-range brands and gives the Ex9N a significant commercial advantage in Saudi Arabia's joint-venture industrial and infrastructure projects where US engineering codes coexist with IEC-based SEC panel standards. Engineered at NOARK's R&D centre in Brno, Czech Republic, the Ex9N 100A delivers a breaking capacity of 36 kA at 415 V AC under IEC 60947-2, covering the prospective fault current levels encountered at the LV main distribution tier in Saudi commercial and industrial buildings. The adjustable thermal-magnetic trip unit provides overload protection from 63% to 100% of In and instantaneous magnetic release at 10× In, allowing precise setting to the downstream cable and equipment thermal limits without replacing the breaker.

The dual IEC 60947-2 and UL 489 certification of the NOARK Ex9N is the product's defining commercial differentiator in the Saudi market. Saudi Arabia's large joint-venture petrochemical, mining, and infrastructure projects — particularly those in King Salman Energy Park (SPARK), Wa'ad Al-Shamal phosphate complex, and the Jazan Economic City — frequently involve US engineering firms, US EPC contractors, or US-standard process equipment that requires UL 489-certified circuit breakers in the electrical distribution system. At the same time, the buildings and utility infrastructure at these same sites must comply with SEC's IEC-based distribution standards. The Ex9N's dual certification resolves this specification conflict in a single product: the same breaker satisfies both the US EPC contractor's UL 489 requirement and the SEC panel approval team's IEC 60947-2 requirement, eliminating the cost and complexity of specifying different breakers for different areas of the same project.

ARAMCO's upstream and downstream facilities in the Eastern Province increasingly encounter this IEC/UL duality challenge as American and European engineering firms collaborate on ARAMCO's multi-billion-dollar expansion projects. The Ex9N 100A's dual certification also holds value in SABIC's joint-venture plants — such as SABIC INNOVATIVE PLASTICS and joint ventures with SINOPEC and ExxonMobil — where the electrical system design may originate from a US engineering house but must ultimately pass SABIC's IEC-aligned panel approval process. NOARK's Czech R&D heritage adds a layer of credibility to this dual-certification claim that pure Chinese manufacturers cannot easily replicate: the Brno R&D centre's European engineering methodology underpins both the IEC and UL certification test programmes. Razz Middle East actively presents the Ex9N dual-certification value proposition to Saudi EPC contractors and electrical consultants working on joint-venture projects.

Razz Middle East stocks Ex9N 100A MCCBs in Saudi Arabia and provides the full dual-standard technical documentation — IEC test certificates, UL listing documents, and SASO conformity declarations — that joint-venture project procurement teams require. Our engineers can provide MCCB selectivity co-ordination studies in both IEC and NEC calculation formats, supporting electrical engineers who must demonstrate protection co-ordination to both SEC inspectors and US-standard project reviewing consultants simultaneously.
