4P 16A Type C 6kA 230-400V RCBO

1) Combined 2-in-1 protection for enhanced safetyThis 4P 16 A miniature residual current circuit breaker combines in a single device protection against overloads and short circuits (circuit breaker function) and protection against insulation faults / current leakage (residual current function). It therefore constitutes an essential barrier against the most common risks in a low-voltage installation: conductor overheating, insulation deterioration, tripping linked to a faulty device, and above all a reduction in the risk of electric shock and electrical fire. It is a relevant choice for users looking for safer and simpler-to-manage distribution, by limiting the number of devices in the consumer unit while retaining the essential protection functions.2) 4-pole format: complete disconnection, ideal for three-phase and circuits to be fully isolatedThe 4P (four-pole) configuration is particularly suited to installations where a clear power cut-off of all the conductors in a circuit is required: three-phase supply (3P+N), small workshops, technical equipment, distribution cabinets, or consumer units requiring more complete isolation during work. In maintenance, this multipole disconnection provides greater peace of mind and reduces the risk of finding part of the circuit still live. In sensitive environments (technical rooms, outdoor enclosures, damp areas), this approach contributes to safer operation and better compliance with good distribution practices.3) Electrical characteristics suited to common uses: 16 A, AC 230-400 V, 50/60 HzWith a nominal rating of 16 A, this model is suitable for circuits frequently found in homes, retail and small commercial premises: sockets and dedicated circuits of moderate power, lighting, small machines and auxiliaries, depending on conductor sizing and consumer unit design. Its AC 230 to 400 V operating range and 50-60 Hz compatibility make it usable on most European networks. It therefore meets the protection needs of standard outgoing circuits in a consumer unit, provided that the choice of rating, cable cross-section and the overall selectivity of the installation are respected.4) C tripping curve: a good balance between service continuity and protectionThe C curve is a very widespread standard in Europe because it offers reasonable tolerance to inrush currents at start-up (for example certain motors, fans, pumps, compressors or power supplies presenting a transient peak), while ensuring rapid disconnection in the event of a fault. This helps limit nuisance tripping when the installation is correctly sized, without sacrificing protection of conductors and equipment. This characteristic makes it a versatile option for many domestic and professional circuits, particularly where a compromise between ease of use and safety is sought.5) 6 kA breaking capacity and EN 61009 compliance: designed for distribution boardsWith a breaking capacity of 6 kA, this circuit breaker is sized to interrupt a significant short-circuit current under the intended conditions, which reinforces the robustness of outgoing circuit protection. Compliance with EN 61009 places it within the framework of RCBO-type devices (circuit breaker with integrated residual current protection), commonly used in Europe in distribution boards. For a choice perfectly suited to personal protection, it is important to check before installation the residual current sensitivity (IΔn, typically 30 mA for standard circuits), data not specified here. It is recommended to entrust wiring to an electrician and to carry out periodic tests (according to the device and installation recommendations) in order to guarantee the proper functioning of the residual current function over time.
