410800 — Legrand DX3 RCBO Residual Current Breaker with Overcurrent
The Legrand DX3 RCBO (Residual Current Circuit Breaker with Overcurrent protection) integrates earth-leakage protection and overcurrent protection in a single 18 mm wide module, combining the functionality of a residual current device (RCD) and a miniature circuit breaker (MCB) into one compact unit. Rated at 6 A to 40 A with a residual current sensitivity of 30 mA, the DX3 RCBO is available in both AC type (detecting sinusoidal earth-leakage currents) and A type (detecting pulsed DC and AC earth-leakage currents from modern switch-mode power supplies, variable speed drives, and EV charging equipment). The device complies with IEC 61008 and IEC 61009-1, making it suitable for final circuits in TN-S, TN-C-S, and TT distribution systems — the three system earthing arrangements most commonly encountered in Saudi Arabian commercial and residential installations.
The DX3 RCBO's A-type variant has become particularly relevant in Saudi Arabia's fast-growing EV charging infrastructure. The Saudi Energy Efficiency Centre (SEEC) and SEC's EV integration roadmap are driving widespread installation of AC wallbox and Type 2 charging stations across residential compounds, commercial parking, and NEOM's mobility corridors. These charging stations generate pulsed DC earth-leakage currents that conventional AC-type RCDs cannot detect reliably, creating a safety gap that the A-type DX3 RCBO specifically addresses. Similarly, the proliferation of variable-frequency drives in HVAC systems across Riyadh's commercial district and in the SABIC industrial support facilities produces pulsed fault currents that require A-type detection for compliant personnel protection in accordance with the Saudi Electrical Code and IEC 60364-4-41.
In healthcare, the DX3 RCBO is the preferred choice for final circuit protection in Saudi Ministry of Health hospital electrical installations, where the combination of high-risk patient environments and the mandated use of IT earthing systems in medical locations (Group 2 per IEC 60364-7-710) requires sensitive, reliable, and type-specific earth-fault detection. KFSH (King Faisal Specialist Hospital), Johns Hopkins Aramco Healthcare, and the new NEOM Smart Health Campus project all specify RCBO protection at the final circuit level. The device's test button permits monthly functional testing by maintenance staff without specialist tools, and the independent reset of the earth-fault and overcurrent functions simplifies fault finding after a trip — important in hospital environments where rapid supply restoration minimises patient care disruption.
Razz Middle East supplies the full DX3 RCBO range in AC and A types, all ratings from 6 A to 40 A, in 1P+N configuration, from local inventory in Riyadh, Jeddah, and Dammam. We offer a full selection and application service — our engineers will recommend the correct type, current rating, and tripping curve for each circuit based on the installation category and load profile, and can provide IEC 61009-1 documentation for Saudi Building Code submissions.

Key Features & Benefits
- Type A residual current detection senses both sinusoidal and pulsed DC earth-leakage currents from EV chargers and VSDs — essential for Saudi Arabia's growing EV infrastructure.
- 18 mm single-module width combines RCD and MCB functions, halving the DIN rail space compared to separate devices and maximising panel density.
- Independent reset buttons for earth-fault and overcurrent functions simplify fault diagnosis and speed supply restoration in hospital and critical facility applications.
- 30 mA sensitivity provides personnel protection in wet areas, bathrooms, and outdoor circuits as required by the Saudi Electrical Code and IEC 60364-4-41.
- B and C tripping curves available to match resistive (lighting) and inductive (motor) loads while maintaining 30 mA earth-fault sensitivity.
- Monthly test button verifies earth-fault protection function without tools — mandatory maintenance check for hospital and residential installations.
Industrial Applications in Saudi Arabia
- EV wallbox and Type 2 charging station final circuit protection in NEOM mobility corridors, PIF commercial parking, and ARAMCO residential compound EV roll-outs.
- Final circuit protection in Saudi Ministry of Health hospital medical locations (Group 2) where IEC 60364-7-710 requires sensitive earth-fault protection.
- Wet area and bathroom circuit protection in NEOM Smart Health Campus, luxury hotel developments in the Red Sea Project and Amaala.
- HVAC VSD branch circuit protection in Riyadh commercial district high-rise towers where pulsed fault currents require A-type RCD detection.
- Residential final circuit protection in SABIC and ARAMCO employee housing compounds requiring Saudi Electrical Code compliance.
- Laboratory and research facility circuit protection in KACST, KFUPM, and NEOM science campuses where sensitive equipment demands combined overcurrent and earth-fault protection.
