What this RCBO does in the panel
It protects a single outgoing final circuit against both overload/short-circuit (thermal-magnetic trip, C-curve) and earth leakage (10 mA sensitivity). The 6 A rating at 50 °C and 10 kA breaking capacity (Icn at 240 V AC, per IEC 61009-2-2) mean it's sized for lighting or small appliance circuits where personnel protection against direct contact is needed — the 10 mA threshold catches leakage through a person before ventricular fibrillation thresholds are reached. The C-curve (magnetic trip 5–10 × In) handles moderate inrush from fluorescent ballasts or small motors without nuisance trips.
Mounting and wiring — what fits the DIN rail
Top terminals accept 1–25 mm² rigid or 1–16 mm² flexible; bottom terminals accept 1–16 mm² rigid or 1–10 mm² flexible. Neutral is on the left (1P + Ns configuration). Tightening torque: 3.5 N·m top, 2 N·m bottom. Wire strip length: 14 mm top, 13 mm bottom.
Standards and documentation
Certified to IEC 61009-1, IEC 61009-2-2, and BS EN 61009-1 — the full suite for RCBOs covering both overcurrent and residual current protection. The 10 mA sensitivity is the lowest standard threshold, used for circuits where additional protection against direct contact is specified (e.g., socket outlets in bathrooms or construction sites). The thermal-magnetic trip unit is field-proven, with 5000 electrical and 20000 mechanical cycles endurance.
