3P 16A C curve 6kA EN61009 400V RCBO

1) Combined “MCB + residual current” protection for enhanced safetyThis modular 3P 16 A residual current circuit breaker with overcurrent protection (RCBO) combines in a single device two essential electrical protection functions: protection against overloads and short circuits (circuit breaker function) and protection against insulation faults/current leakage (residual current function). In the event of an issue on the installation (overheating linked to excessive current, short circuit, risk of indirect contact: earth leakage, ageing insulation, moisture, damaged cable), the device quickly cuts the power supply, limiting the risks of electrically caused fire, damage to equipment and electric shock. This all-in-one approach is particularly appreciated in consumer units where clear, readable and effective protection is sought, without multiplying modules.2) Practical modular format: simplified wiring and easier maintenanceBy integrating the circuit breaker part and the residual current part into the same product, this model allows a cleaner consumer unit architecture: fewer devices to connect, simpler identification of outgoing circuits, and generally faster subsequent work (diagnosis, replacement, extension). It is a relevant choice when you want to avoid the circuit breaker + residual current switch combination on the same outgoing circuit, particularly in installations where you want to isolate a circuit precisely in the event of a fault, while retaining complete protection. In common uses, faults may come from ambient moisture, an appliance whose insulation deteriorates over time, or a pinched/abraded cable: the residual current function then provides an additional layer of safety beyond magnetic thermal protection alone.3) Technical characteristics suited to common installations (Europe)This product is a 3-pole (3P), 16 A unit, intended for AC 223/230 V to 400 V networks, at 50–60 Hz, with C tripping curve and a breaking capacity of 6 kA. It is stated to comply with EN 61009.- 3P: simultaneous disconnection of three conductors/phases, useful for three-phase outgoing circuits or circuits requiring coordinated disconnection- 16 A: common rating for moderate-power outgoing circuits (depending on cable cross-section, installation method, thermal constraints and local rules)- C curve: a compromise for general-purpose uses (lighting, sockets, switch-mode power supplies, small motors), tolerates start-up current inrush better than a B curve while remaining protective- 6 kA: breaking/withstand level common in residential and small commercial settings, to be selected according to the prospective short-circuit current at the installation point4) Typical applications: housing, small commercial premises, retail, equipment outgoing circuitsThis 3P 16 A residual current circuit breaker with overcurrent protection is suitable for domestic consumer units (depending on the installation architecture), offices, small shops, light workshops, as well as circuits dedicated to small equipment when multipole disconnection is required. The benefit of a 3P unit is to reduce the risk of leaving one phase live in the event of a fault and to offer more consistent management of outgoing circuits. It can be used for varied loads (small motors, pumps, ventilation, technical circuits), subject to checking the consistency between the 16 A rating, conductor cross-section, line length, installation method and the requirements applicable on site (NF C 15-100 in France or project-specific requirements). For more demanding environments (near a transformer, high power levels), the required breaking capacity should be validated.5) Points to note before purchase/installation: residual current settings and suitability complianceCertain key information is not specified here, notably the rated residual operating current IΔn (for example 30 mA for personal protection in many cases, or 100/300 mA depending on the strategy). Before installation, it is recommended to check the rating plate of the model received (IΔn, any selectivity, wiring diagram, network compatibility). Installation should ideally be carried out by a qualified electrician, because incorrect wiring can neutralise the residual current protection or cause nuisance tripping. If the device has a test button, periodic checking according to maintenance practices helps ensure correct operation.Summary: 3P, 16 A, C curve, 6 kA, EN 61009, complete and rational protection of outgoing circuits.
