A9R11425 — Schneider Electric Acti9 iDT40N RCCB
The Schneider Electric Acti9 iDT40N RCCB (Residual Current Circuit Breaker) is a pure earth leakage protection device covering 25 A to 100 A in 2P and 4P pole configurations for group protection of multiple final circuits in residential and commercial electrical distribution boards. The iDT40N RCCB is installed upstream of a group of MCBs to provide blanket earth leakage protection for that group, offering a cost-effective approach to RCD protection where individual RCBO per circuit is not required or cost-justified. Sensitivity options of 10 mA, 30 mA, 100 mA, and 300 mA cover applications from personnel shock protection (30 mA) to fire prevention (300 mA) and supplementary equipotential bonding zone protection (10 mA).
The iDT40N incorporates immunity to high-frequency leakage currents from electronic equipment — a critical feature in Saudi Arabia's modern commercial buildings populated with variable frequency drives, LED drivers, UPS systems, and IT equipment that generate high-frequency leakage current on the earth conductor that can cause nuisance tripping of low-discrimination RCCBs. The device's immune frequency response above 2 kHz prevents these nuisance trips while maintaining sensitivity to power frequency fault currents. The 4P variant covers three-phase and neutral fault detection for three-phase circuits, protecting three-phase motors and equipment supplied from three-phase distribution boards.
In Saudi Arabia, the iDT40N RCCB KSA is the standard group RCD protection device specified in SEC-approved residential and commercial distribution board designs. Every residential consumer unit in new construction under the Saudi Building Code requires at least one RCCB protecting all socket outlet and bathroom circuits. Commercial distribution boards in shopping malls, office buildings, and hotels use 4P iDT40N to provide ground fault protection for tenant three-phase and single-phase circuits. NWC and ARAMCO residential compound distribution boards use the iDT40N for fault protection on all plug socket circuits.
Razz Middle East stocks iDT40N RCCBs in all standard ratings (25 A to 100 A), both 2P and 4P configurations, and all sensitivity levels (30 mA and 300 mA most common) for same-day supply.

Key Features & Benefits
- High-frequency leakage current immunity above 2 kHz prevents nuisance tripping from VFDs, LED drivers, UPS, and IT equipment in modern commercial buildings, while maintaining full sensitivity to power-frequency fault currents.
- Four sensitivity levels (10/30/100/300 mA) cover personnel shock protection (30 mA), fire prevention on long cable routes (300 mA), and high-sensitivity supplementary bonding zones (10 mA) within a single product range.
- 4P four-pole variant detects earth faults on three-phase and neutral conductors, covering three-phase motor circuits and three-phase distribution in commercial and industrial buildings.
- Group protection of multiple MCB circuits from a single upstream RCCB provides cost-effective RCD coverage where individual RCBO per circuit would significantly increase panel cost and space.
- Test button verifies RCCB tripping function for IEC 61008-1 monthly test compliance, providing a simple site verification procedure without requiring test instrumentation or power interruption to protected circuits.
- 25 A to 100 A current rating covers group protection from small domestic consumer units to large commercial distribution boards, spanning the full residential and commercial sub-main circuit range in Saudi buildings.
- Compatibility with Acti9 iC60N/H MCBs on the downstream side enables coordinated and space-optimised Acti9 distribution board assemblies from a single product family with matched physical dimensions.
Industrial Applications in Saudi Arabia
- Residential villa and apartment consumer unit group RCD protection across ROSHN, DARA, and private housing developments, providing Saudi Building Code mandated socket and bathroom circuit earth leakage protection.
- Commercial office building tenant distribution board three-phase group protection using 4P iDT40N, covering three-phase power circuits and single-phase socket outlets under a single upstream RCD protection device.
- Shopping mall and retail facility distribution board group protection in Riyadh, Jeddah, and Dammam malls, where high-frequency immunity prevents nuisance tripping from the dense population of electronic equipment.
- Hotel room cluster distribution boards in Makkah Haram hotels and Madinah hospitality facilities, where group protection balances cost efficiency with Saudi Building Code earth fault protection requirements.
- NWC and ARAMCO residential compound distribution boards providing earth leakage group protection to residential accommodation for operations personnel at Eastern Province and industrial city facilities.
- School and institutional building distribution boards under Ministry of Education construction programme, where group RCCB protection satisfies Saudi electrical code earth leakage requirements for educational buildings.
- Industrial facility office and welfare building distribution boards at MODON industrial estates, where separate 30 mA RCCB groups for welfare areas and 300 mA groups for heavy equipment circuits provide selective protection.
