2P 40A C Curve 6kA Residual Current Circuit Breaker EN61009

1) 2-in-1 protection: circuit breaker + residual current protection, for complete safety in a single moduleThis 2P C40A miniature RCBO combines in one device magnetothermal protection (overload and short-circuit) and residual current protection (current leakage/risk of electric shock). In practical terms, it automatically cuts off the power supply when the current becomes abnormally high (too many devices on one circuit, gradual overheating, major fault) or when a leakage to earth appears (ageing insulation, damaged cable, humidity, indirect contact). This all-in-one approach is particularly appreciated in France for improving clarity in the consumer unit, limiting multiple assemblies and reducing risks linked to complex connections. Result: a better protected circuit, clearer disconnection in the event of an incident, and a higher perceived level of safety in both domestic and professional environments.2) 2P double-pole disconnection: clearer isolation of the circuit (live + neutral)Thanks to its 2-pole (2P) configuration, the device allows simultaneous disconnection of the circuit conductors (often live and neutral depending on the installation layout). In practice, this provides a more definite power isolation during tripping or intervention, which suits installation and maintenance practices on domestic and light commercial consumer units. This choice is relevant for circuits where more intuitive safety and diagnostics are desired: if the device trips, it is immediately clear that the fault concerns this outgoing circuit, and the circuit isolation is more obvious. This double-pole disconnection also contributes to greater peace of mind during inspection, troubleshooting or replacement operations on downstream equipment, in compliance with electrical safety rules.3) 40 A rating and C curve: a balance for versatile circuits and loads with inrush currentWith a rated current of 40 A, this RCBO is intended for outgoing circuits requiring a higher current-carrying capacity (to be sized according to conductor cross-section, circuit type and the actual power demand). Its C tripping curve is generally preferred for standard circuits, as it better tolerates certain inrush currents at start-up (motors, compressors, light electromechanical equipment) than a more sensitive curve, while still maintaining effective protection in the event of prolonged overload or short-circuit. This helps limit nuisance tripping linked to appliance start-up, without sacrificing protection. For optimum results, a choice consistent with the wiring and intended use of the circuit is recommended, rather than selecting a high rating for convenience.4) Compliant with EN 61009, 6 kA breaking capacity: suitable for residential and light commercial consumer unitsDesigned in accordance with EN 61009, this product meets the expected requirements for devices combining circuit breaker and residual current protection. Its 6 kA breaking capacity indicates its ability to interrupt a high short-circuit current under standardised conditions, a level commonly sought for housing, retail, small workshop or secondary outgoing circuit installations, where short-circuit studies and network architecture allow it. In the event of a sudden fault, the device is designed to open the circuit safely, which helps limit overheating, conductor deterioration and the risk of electrically caused fire. Protection is not limited to staying closed: above all, it must trip correctly when the situation requires it.5) Wide network compatibility (AC 230–400 V, 50/60 Hz) and recommended uses: home, retail, damp areasCompatible with AC 230–400 V and 50/60 Hz networks, this miniature RCBO integrates into the majority of standard power supply configurations. It is particularly relevant on circuits where enhanced prevention against insulation faults is sought: kitchen, bathroom, utility room, garage, basement, outdoor sockets, technical rooms, or areas where appliances with metal casings are handled. By combining overcurrent protection and residual current protection, it simplifies consumer unit organisation, helps keep the installation clear, and makes fault location easier (one outgoing circuit = one complete protection device). For installation in accordance with best practice, it is recommended to entrust fitting to a qualified person and to comply with circuit sizing requirements (conductors, tightening, enclosure ventilation).Note: as the rated residual operating current (e.g. 30 mA/100 mA) and certain physical details (dimensions, presence of a test button, etc.) are not specified, they are not mentioned here. If you provide them, I can adapt the description as closely as possible to the expectations of the French market.
