NOARK Ex9M 3P 63A C-Curve Miniature Circuit Breaker

The NOARK Ex9M 3P 63A C-Curve Miniature Circuit Breaker (model 100332) is a three-pole IEC 60898-1 / IEC 60947-2 protective device engineered at NOARK's Brno, Czech Republic R&D facility and certified by TÜV to a breaking capacity of 10 kA at 400 V AC three-phase. Operating on the C-curve (5–10× In) magnetic release characteristic, the 63A three-pole rating is the top-of-range MCB commonly used as the main protective device for small distribution sub-panels, motor protection for pumps up to approximately 18.5 kW, and three-phase power outlets in light industrial facilities, workshops, and large commercial kitchens. At 10 kA breaking capacity, the Ex9M 63A handles the prospective fault current levels encountered at the secondary distribution tier of Saudi Arabia's 380 V three-phase network as distributed through SEC-connected low-voltage panels.

The 3-pole configuration and 63 A rating of the Ex9M 100332 make it particularly suited to the Saudi industrial and commercial sector where three-phase loads are ubiquitous — from small air compressors and workshop machinery to three-phase HVAC units, refrigeration compressors, and sub-panel incomers for tenant distribution boards in multi-storey commercial developments. The TÜV certification is a decisive advantage in the ARAMCO and SABIC procurement ecosystem, where the SAPID (Saudi Aramco Product Identification) process requires that protection devices carry third-party certification from a body approved under the ARAMCO approved-vendors framework. NOARK's TÜV documentation satisfies this requirement and has been successfully submitted in multiple ARAMCO facilities management project data packages in the Eastern Province.

Saudi Arabia's Vision 2030 giga-project pipeline — covering NEOM, Qiddiya, The Rig, Red Sea Project, and the expanding King Salman Energy Park (SPARK) in Jubail — creates sustained procurement demand for mid-range quality three-phase MCBs that are fully IEC-certified but commercially competitive versus premium European brands. The NOARK Ex9M 63A 3P fills precisely this requirement: it offers the Czech R&D design heritage and TÜV third-party certification that consulting engineers and ARAMCO/SABIC procurement teams require, while providing the 20–30% cost advantage over premium European alternatives that project cost management teams seek as Vision 2030 projects compete on tight construction budgets. SASO compliance is maintained through the IEC 60898-1 certification basis, which aligns with SASO 2203.

Razz Middle East stocks Ex9M three-pole MCBs locally in Saudi Arabia, supporting panel builders who require urgent delivery for panel manufacture or site replacement. Our technical team can prepare full co-ordination studies and selectivity analyses for mixed-brand panel installations incorporating NOARK Ex9M breakers alongside downstream RCBOs or upstream MCCBs from other manufacturers. We provide Arabic-language conformity declarations and SASO import documentation to support SEC and MOMRA panel approval submissions, and offer on-site training for panel shop teams commissioning NOARK products for the first time.
