2P 20A Type C 6kA Residual Current Circuit Breaker EN61009

1) Complete 2-in-1 protection for low-voltage installationsThis 2P 20 A miniature residual current circuit breaker with overcurrent protection (RCBO) combines in a single device protection against overloads and short circuits (circuit breaker function) and protection against insulation faults / current leakage (residual current function). In practical terms, it helps prevent two major everyday risks: overheating of conductors, nuisance tripping or damage linked to an overload/short circuit, and the risk of electric shock in the event of leakage to earth on an appliance or wiring. Ideal for renovation as well as new installations, it provides an additional level of safety on a dedicated line (sockets, lighting, small equipment), while simplifying the consumer unit by limiting the number of modules to install and wire.2) 2P format: simultaneous phase + neutral disconnection, clearer and saferThe 2-pole (2P) configuration allows simultaneous disconnection and protection of two conductors, generally phase and neutral. This choice is appreciated in domestic and small commercial consumer units when more complete isolation of the circuit is desired during work, and more consistent neutral management on the protected line. In many contexts (homes, offices, shops), this architecture makes troubleshooting clearer, strengthens maintenance safety and avoids situations where one conductor would remain partially live. The 20 A rating corresponds to common outgoing circuit protection for standard circuits, provided that the conductor cross-section and the use of the circuit are correctly sized.3) Network compatibility and stable operation: 230–400 V AC, 50/60 HzDesigned for the most common power supply environments, this RCBO operates on AC 230 V to 400 V and accepts a frequency of 50–60 Hz, making it suitable for typical residential and commercial installations. Once fitted in a distribution board or control enclosure, it provides reliable long-term protection: home, small shop, office, technical room, machine enclosure or control enclosure. This versatility also makes it easier to replace an existing device during a consumer unit upgrade, particularly when moving from a standard circuit breaker to a solution that also integrates the residual current function.4) 6 kA breaking capacity and C curve: the right balance for everyday usesWith a breaking capacity of 6 kA, the device is sized to interrupt a high short-circuit current and limit the consequences of a severe fault on conductors and equipment. The C tripping curve, very common in Europe, better tolerates the inrush currents of certain devices (small motors, power supplies, transformers, capacitor-based equipment), reducing the risk of unwanted tripping, while maintaining a fast response in the event of a genuine overload or short circuit. Result: more convenient day-to-day protection, without compromising safety.5) EN 61009 compliant, recommended uses and selection/installation adviceCompliant with EN 61009 (residual current circuit breakers with overcurrent protection), this product fits easily into a maintenance and replacement approach in a European environment. It is recommended for: socket outgoing circuits in a home, supplementary lines in a kitchen/bathroom, circuits in an office or shop (printers, tills, water dispensers, air conditioning on a dedicated socket), and control enclosures for small equipment where the C curve improves tolerance to start-up currents. For a relevant choice, check that 20 A is suitable for the circuit (power, cable cross-section, installation method). Large heating appliances (oven, hob, water heater) often require a dedicated outgoing circuit sized specifically. Finally, as installation in a consumer unit is an operation in a potentially dangerous environment, installation by a qualified electrician is strongly recommended (tightening, phase/neutral identification, earth continuity, circuit compliance).
