NOARK Ex9ML 1P+N 16A 30mA RCBO

The NOARK Ex9ML 1P+N 16A 30mA RCBO (model 110626) combines Class A residual current protection at 30 mA sensitivity with thermal-magnetic overcurrent protection at 16 A in a single 1P+N module that occupies only two 18 mm pole-widths on a 35 mm DIN rail. Engineered at NOARK's R&D centre in Brno, Czech Republic, and certified to IEC 61008-1 and IEC 60898-1, the Ex9ML provides both earth fault protection at the 30 mA threshold required by IEC 60364 for socket outlet and bathroom circuits and overcurrent/short-circuit protection in a single device — eliminating the need for separate RCD and MCB devices in each protected circuit and substantially reducing panel real estate in domestic and commercial distribution boards.

The 30 mA residual current threshold is the international standard for personal protection against electric shock in circuits serving accessible socket outlets, bathroom equipment, wet areas, and portable tool power supplies. In Saudi Arabia, NEC-derived and IEC-based electrical codes both mandate 30 mA RCD or RCBO protection for bathroom circuits and outdoor socket outlets in residential, commercial, and hospitality buildings. The Saudi Electricity Company's distribution network standards, referenced in SASO technical regulations for building electrical installations, require RCBO or RCD protection in all circuits serving wet zones and socket outlets in public access areas — a requirement that the Ex9ML 16A satisfies in a single space-efficient device that simplifies panel wiring. The TÜV-certified design documentation of the Ex9ML series is accepted in ARAMCO panel approval packages for residential compound wiring.

The Saudi hospitality and tourism construction boom driven by Vision 2030 — including Amaala, Red Sea Project's Shura Island and Umaiq Bay hotel clusters, Diriyah's boutique hotel district, and the expanded Holy Sites accommodation zones in Mecca and Medina — creates large-scale demand for RCBOs in hotel room distribution boards. Each hotel room in a modern Saudi hospitality development typically requires 4–8 RCBO-protected circuits, meaning a 500-room hotel consumes 2,000–4,000 RCBO units in its distribution panels. NOARK's Ex9ML 16A provides the IEC-certified, TÜV-documented quality that five-star hotel project consultants specify, while the Czech R&D brand positioning allows Razz Middle East to offer meaningful cost savings versus ABB DS201 or Schneider RCBO equivalents at the procurement scale that large hospitality projects generate.

Razz Middle East maintains local Saudi stock of the Ex9ML series across standard ratings for same-week delivery to hotel panel fabrication shops in Riyadh, Jeddah, and Dammam. Our technical team provides co-ordination studies for mixed RCBO/RCD/MCCB panels, SASO import documentation, and Arabic-language conformity declarations to support project electrical consultant approvals and SEC distribution board submission packages.
