The 100 mA earth leakage sensitivity is sized for circuits where a lower 30 mA threshold would cause nuisance tripping — typically distribution sub-mains, lighting circuits, or equipment with natural leakage. This is a 1P+N device — it switches the live pole and monitors the neutral for leakage, but does not disconnect the neutral on overcurrent. The clip-on mounting snaps onto standard DIN rail, occupying 2 × 9 mm pitches (18 mm total width). The RCBO is certified to BS EN 61009-1, the harmonized standard for residual current operated circuit breakers with integral overcurrent protection. It is rated for TN earthing systems and is suitable for isolation — the contact position indicator confirms the state of the main contacts. The device is tropicalised (class 2) for use in high-humidity environments up to 95% RH at 55 °C. The limitation class 3 indicates the RCBO limits let-through energy during a fault, reducing stress on downstream equipment. The toggle control provides local ON/OFF indication and the device can be padlocked (Ø 4 mm padlock) for lockout/tagout during maintenance.","metaTitle":"Schneider Electric A9D18840 IKQE RCBO, 40 A, 10 kA, 100 mA,","metaDescription":"Schneider Electric A9D18840 Acti9 IKQE RCBO, 40 A rated current, 10 kA breaking capacity, 100 mA earth leakage, C-curve, 1P+N, DIN rail mount.
