NOARK Ex9ML 1P+N 25A 30mA RCBO

The NOARK Ex9ML 1P+N 25A 30mA RCBO (model 110632) is a dual-function protective device combining 30 mA Class A residual current earth-fault protection with 25 A C-curve thermal-magnetic overcurrent and short-circuit protection in a single compact 1P+N module occupying two 18 mm pole positions on a standard 35 mm DIN rail. Designed at NOARK's R&D centre in Brno, Czech Republic, and certified by TÜV to IEC 61008-1 and IEC 60898-1, the 25 A variant extends the Ex9ML range to cover higher-demand single-phase circuits — particularly air conditioning units, immersion water heaters above 3.5 kW, and dedicated power circuits for catering equipment — where the 16 A rating would be undersized but the load characteristics still require combined RCD and overcurrent protection in a single panel device.

The 25 A rating is calibrated for the split-system and multi-split air conditioning circuits that dominate single-phase electrical loads in Saudi Arabia's residential and hospitality sectors. A typical 12,000–18,000 BTU (1.0–1.5 ton) split-system air conditioner draws 8–12 A in steady-state operation with start-up inrush currents in the 25–40 A range, placing it squarely in the protection zone of a 25 A C-curve RCBO. The Ex9ML 110632 provides simultaneous protection against the electrical shock risk from earth faults in the AC unit's condensate drainage circuit or outdoor unit wiring, and against overload or short-circuit faults in the supply cable — a dual-function that Saudi residential and hotel electrical engineers routinely specify in final circuit design. SASO technical building regulations mandate RCD protection for circuits in wet zones and accessible locations, and the Ex9ML 25A satisfies this requirement in a single compact device.

Saudi Arabia's luxury hospitality sector — driven by Vision 2030's target of 150 million tourist visits annually and the massive hotel construction pipeline from Red Sea Project, Amaala Ultra-Luxury Resort, and the expanded Grand Mosque accommodation zone in Mecca — procures RCBO devices at scale for hotel room and suite distribution boards. A luxury hotel project of 300–500 rooms typically specifies 25 A RCBO-protected circuits for room AC units and bathroom water heating circuits, creating procurement demand for hundreds of units per project. NOARK's Ex9ML 25A provides the TÜV-certified European design quality that five-star hotel project management consultants require in their electrical panel specifications, while offering the cost advantage that giga-project procurement managers are actively seeking as Vision 2030 projects face cost escalation pressures. Razz Middle East's Czech R&D narrative for NOARK allows specification substitution presentations to consulting engineers that are technically credible.

Razz Middle East carries Ex9ML 25A units in local Saudi warehouse stock and can fulfil purchase orders from Riyadh, Jeddah, Dammam, Mecca, Medina, and Jubail within 48 hours. We provide full SASO import documentation, Arabic-language conformity declarations, and circuit co-ordination data sheets to support panel approval submissions to Saudi consulting engineers and SEC distribution network connection teams.
