4P RCBO 63A AC230-400V 6kA C Curve EN61009

1) Complete 2-in-1 protection: overload/short-circuit + insulation fault (earth leakage)This 4P 63 A miniature RCBO combines, in a single device, magnetic-thermal protection (against overcurrents caused by overloads and short-circuits) and residual current protection (cut-off in the event of current leakage linked to an insulation fault, humidity, cable ageing or indirect contact). This double level of safety helps reduce the risk of electric shock and electrically caused fire, particularly in circuits where fast cut-off is desired as soon as an anomaly appears. Ideal for securing a domestic or light commercial installation, where you do not just want a circuit breaker that trips, but more comprehensive and more reassuring protection on a daily basis.2) 4P format: simultaneous disconnection of conductors for three-phase networks and multi-conductor installationsThe 4-pole (4P) design is particularly suited to three-phase + neutral (3P+N) configurations and, more generally, to any installation where several conductors need to be isolated in a single operation. In maintenance, this point is crucial: total disconnection limits the risk of one conductor remaining live by mistake. The 4P format is also appreciated in the distribution boards of houses, shops, offices, small workshops and in the electrical cabinets of technical premises, when safer and clearer management of outgoing electrical circuits is required.3) Main electrical characteristics suited to common uses in EuropeRating: 63 A, for circuits and wiring sized accordingly (the choice of rating must remain consistent with conductor cross-section, installation method, ambient temperature and appliance starting currents).Operating voltage: AC 230 to 400 V (depending on product marking), covering most residential power supplies and many light commercial needs.Frequency: 50/60 Hz, compatible with standard networks.These features make it a relevant solution for protecting dedicated lines (water heater, air conditioning, light workshop, kitchen equipment, specialised sockets, etc.) or certain sensitive outgoing circuits requiring residual current protection, in addition to suitable upstream protection.4) Breaking performance and start-up behaviour: 6 kA + C curve to limit nuisance trippingWith a breaking capacity of 6 kA, the device is sized for many sub-distribution boards and standard uses (housing, retail, offices), provided that the prospective short-circuit level at the installation point remains compatible with the installation. The C tripping curve offers a good compromise: it better tolerates current peaks at start-up (small motors, compressors, power supplies, fans, low-power transformers) than a B curve, which helps avoid nuisance tripping, while remaining suitable for the most common uses (lighting, sockets, mixed equipment).5) EN 61009 compliant, integration advice and points to check before purchase (to avoid any selection error)The device is stated to comply with EN 61009 (a common European reference for RCBO-type residual current circuit breakers). For a reliable installation, it is recommended to entrust wiring to a qualified electrician, to check the available space on the DIN rail and terminal compatibility with the conductor cross-section. Important point before confirming your order: the rated residual operating current (e.g. 30 mA / 100 mA / 300 mA) is not specified in the information provided; however, this parameter determines the use (personal protection vs. fire/equipment protection) and sensitivity to tripping. For a result that matches your needs, also make sure it is suitable for your distribution scheme (single-phase or three-phase, presence of neutral, selectivity with the upstream device, short-circuit current at the installation point).
