RCBO Residual Current Circuit Breaker with Overcurrent Protection 2P 10A Type C 6kA EN61009

1) Combined 2-in-1 protection (RCBO): overload/short-circuit + earth leakageThis miniature residual current circuit breaker with overcurrent protection (RCBO) combines in a single device magneto-thermal protection (against overloads and short-circuits) and residual current protection (against insulation faults and the risk of electric shock). It is perfectly suited to domestic consumer units and small commercial installations (office, shop, light workshop), to protect circuits such as lighting, low-power sockets, circuits dedicated to local equipment, etc. In the event of a fault (overheating due to overload, direct short-circuit or current leakage linked to damp or wear of an appliance), it cuts off the power supply quickly, helping to reduce the risk of fire of electrical origin and electric shock. Its all-in-one format also saves space in the enclosure compared with the combination of separate devices, while offering a reassuring level of safety for users looking for a complete solution in a single module.2) 2P (double-pole): simultaneous disconnection of live + neutral for enhanced safetyThe 2-pole (2P) design ensures switching and protection on two conductors, with simultaneous disconnection generally used when both the live and neutral need to be interrupted. This architecture is particularly appreciated on lines where the safety requirement is higher: damp areas (utility room, bathroom), outdoor circuits, outbuildings, frequently handled equipment, or outgoing ways where any residual presence of voltage is to be avoided. In practice, 2P helps to achieve a more complete isolation of the circuit, limiting situations of backfeed or partial energisation that can complicate troubleshooting or increase the risk during work. It is a relevant choice for installations that prioritise a clean disconnection and uniform protection of conductors, particularly in the context of small consumer units or compact control enclosures.3) 10 A rating: ideal for light circuits (lighting, ventilation, small appliances)With a rated current of 10 A, this model is intended for common low to medium current uses: lighting, mechanical ventilation or fans, light automation, sockets dedicated to low-consumption appliances, or socket circuits segmented by area. The 10 A rating is often chosen when a more selective arrangement of outgoing ways is desired and to limit the energy available in the event of a fault on a specific branch. For highly consuming loads (high-power electric heating, water heater, hobs, air conditioning, heavy tools), it is recommended to check the actual current and the conductor cross-section before selection, in order to avoid repeated tripping or operation too close to the limit. This product is therefore primarily intended for comfort circuits and small dedicated lines, where 10 A protection provides a good compromise between availability and safety.4) C curve: better tolerance to inrush current, versatile useFeaturing a C tripping curve, this circuit breaker is designed to withstand moderate inrush currents (starting of small motors, fans, transformers, switch-mode power supplies) without nuisance tripping, while reacting quickly in the event of a short-circuit. Compared with a B curve, the C curve generally offers more convenience on circuits with loads that have a peak at start-up, making it a versatile option for many residential and small commercial outgoing ways. It is also suitable for purely resistive loads (LED lighting with drivers, small appliances, mixed circuits), when stable day-to-day behaviour is desired. This choice of curve is particularly relevant if your circuit supplies, even occasionally, equipment likely to cause a brief but marked inrush current.5) Compatibility and compliance: AC 230-400 V, 50/60 Hz, 6 kA, EN 61009 standardDesigned to operate on AC 230 to 400 V networks (50/60 Hz), this RCBO integrates into the majority of power supply configurations found in Europe. Its 6 kA breaking capacity provides a safety margin suited to domestic consumer units and small commercial installations, where short-circuit currents generally remain controlled but still require reliable breaking capacity. The product is stated to comply with EN 61009, the reference standard for RCBOs with overcurrent protection, making integration easier in projects where regulatory compliance and clear characteristics are important. For genuinely effective residual current protection, the installation must be carried out in accordance with good practice (live and neutral connection in line with the markings, tightening to torque if required, quality earthing) and ideally by a qualified person. Periodic tests in accordance with the installation’s maintenance practices help maintain an optimal level of safety over time.
