3P 63A C curve residual current circuit breaker 6kA 230-400V EN61009

1) 2-in-1 protection: circuit breaker + residual current device (RCBO)This 3P 63 A miniature circuit breaker incorporates protection against overloads and short circuits, as well as residual current protection (earth leakage). In the event of a fault, it trips quickly to cut the power supply and limit conductor heating, damage to equipment and the risk of electric shock. A practical solution for securing an outgoing circuit on the distribution board without multiplying devices, with complete protection on a single line.2) Simultaneous disconnection of the 3 poles: ideal for three-phase and 3-wire circuitsThe 3P (3-pole) design allows three conductors to be isolated and protected in a single operation, suitable for three-phase installations (or certain technical outgoing circuits requiring grouped disconnection). This synchronised disconnection reduces situations of abnormal operation (imbalances, fault on one phase, etc.) and makes operation easier: a single device to identify, a single control point, simpler maintenance and clearer wiring.3) C tripping curve: day-to-day stability, fewer nuisance tripsWith a C curve, this model is suitable for common uses: lighting, sockets, small motors, air conditioning, pump auxiliaries, etc. The C curve better tolerates inrush currents at start-up, which helps to avoid unnecessary power cuts while maintaining effective protection against overcurrents. Reactive protection when needed, more stable day to day in commercial buildings, retail or small industry.4) 6 kA breaking capacity: enhanced safety in the event of a short circuitThe 6 kA breaking capacity indicates the device's ability to interrupt a high fault current during a short circuit, with a level of safety suited to standard distribution outgoing circuits. This characteristic improves resistance to electrical stresses and the reliability of protection in a distribution board. For installations close to a source (transformer, high-power incoming supply) where the short-circuit current may be higher, sizing by a professional remains recommended.5) Network compatibility and compliance: AC 230-400 V, 50/60 Hz, EN 61009 standardDesigned for AC 230 to 400 V and 50/60 Hz networks, this miniature residual current circuit breaker fits into many domestic, commercial or technical boards, particularly in modular enclosures on DIN rails. The EN 61009 standard applies to residual current circuit breakers (RCBOs) combining residual current protection and overcurrent protection. For reliable installation, have the installation carried out by a qualified electrician, follow wiring rules (neutral/earth, associated circuits, conductor cross-sections) and plan periodic inspection (tightening, overheating, test if available).
