RCBO Residual Current Circuit Breaker 1P+N C25A 6kA EN61009

1) Combined “all-in-one” protection (RCBO) for domestic and commercial distribution boardsThis 1P+N miniature residual current circuit breaker with overcurrent protection (RCBO), curve C, 25 A combines in a single module protection against overloads and short circuits (circuit breaker function) as well as residual current protection against earth leakage currents (anti-electrocution / fire prevention function). It is designed to protect a dedicated line in an electrical distribution board (home, office, shop, small technical room). In the event of a fault (overcurrent, insulation fault, leakage on a metal casing), it trips quickly in order to limit the risks of overheating, fire starting and electric shock. This combined solution is valued for saving space in the board while maintaining complete protection and simplified maintenance, line by line.2) 1P+N configuration: clearer disconnection and safer isolation in single-phaseThe 1P+N configuration is designed for single-phase circuits. It allows the phase (L) and neutral (N) to be controlled and isolated (depending on the product architecture), which improves safety during troubleshooting or lockout. Compared with disconnection limited to the phase, 1P+N makes circuit identification easier, reduces ambiguous situations and contributes to a more explicit power disconnection of the protected line. A relevant choice for clearly identified outgoing circuits: kitchen, bathroom, dedicated sockets, specific equipment.3) 25 A rating, curve C: suited to common uses with moderate inrush currentsWith a nominal rating of 25 A (C25) and a C tripping curve, this RCBO is suitable for circuits with standard loads (sockets, lighting, small appliances) and equipment with startup inrush current (certain motors, pumps, small compressors, ventilation units). The C curve protects effectively while limiting nuisance tripping. The choice of 25 A must remain consistent with the installation (conductor cross-section, installation method, line length, simultaneous power). It is recommended to size the circuit with a reasonable margin to avoid repeated disconnections under continuous load.4) Compliance and electrical performance: EN 61009, 6 kA, network compatibilityThis model is stated to comply with EN 61009. It offers a breaking capacity of 6 kA, suitable for most residential installations and small commercial sites at the end of the line. It is compatible with AC 50/60 Hz networks and stated for an AC voltage range of 2230 V–400 V, covering common configurations depending on the distribution scheme and installation context.5) Typical applications and installation recommendationsIdeal for protecting a dedicated line: kitchen sockets, bathroom / utility room (washing machine, water heater, appliances with metal enclosure), light workshop, small shop or office, as well as any circuit where protection of people and conductors is to be combined within a reduced space requirement. Installation must be carried out by a qualified person, with verification of tightening, circuit identification and functional tests after fitting. In the event of repeated tripping, it is advisable to look for the cause (faulty appliance, damp, degraded insulation, loose connection) rather than forcing re-energisation. Splitting the circuits (kitchen, bathroom, lighting, general sockets, dedicated equipment) also makes diagnosis easier and avoids the “everything goes off” scenario.
