Rated 63 A (In) at 220-240 V AC, 50/60 Hz — this is the continuous load current the RCCB carries without derating. The 300 mA earth-leakage sensitivity is a common specification for sub-distribution boards feeding multiple socket outlets or fixed equipment; it provides fire and shock protection while avoiding nuisance tripping from normal leakage in long cable runs or filtered loads. Instantaneous trip (no intentional delay) means the device clears a ground fault within the response time required by EN/IEC 61008-1 — typically under 300 ms at rated residual current, faster at higher fault currents. The 4 kV impulse withstand voltage (Uimp) and pollution degree 2 rating confirm it is suitable for standard indoor distribution panels where transient overvoltages are controlled by upstream SPDs. Terminals accept 1-35 mm² rigid or 1-25 mm² flexible conductors with a 3.5 Nm tightening torque; wire stripping length is 14 mm. The biconnect design allows looping through the same terminal for daisy-chaining outgoing circuits — common in distribution board wiring. Designed and certified to EN/IEC 61008-1 and EN/IEC 61008-2-1 — the harmonized European standard for residual current operated circuit-breakers without integral overcurrent protection. VDE quality label is listed, confirming independent testing and certification by the German testing institute. The 8/20 µs impulse withstand rating of 200 A per EN/IEC 61008-1 means the device survives common lightning-induced surge currents without nuisance tripping or damage — a practical concern in outdoor-fed distribution boards.","metaTitle":"Schneider Electric A9Z03263 Acti9 ID K RCCB, 63 A, 300 mA, 2","metaDescription":"Schneider Electric A9Z03263 Acti9 ID K RCCB, 63 A rated current, 300 mA Type A earth leakage, 2P, DIN rail mount, EN/IEC 61008-1.
