3P 25A C 6kA AC230-400V EN61009 RCBO

1) 2-in-1 protection: circuit breaker + residual current protection (RCBO)This 3P 25 A modular circuit breaker with integrated residual current protection combines in a single device protection against overloads and short circuits (magnetothermal tripping) and protection against insulation faults / current leakage. In the event of earth leakage, deteriorated insulation (moisture, ageing cables) or accidental contact with a live part, it quickly cuts off the power supply, helping to reduce the risk of electric shock and fire of electrical origin. It is a practical solution for securing an outgoing circuit from the distribution board without multiplying modules, while maintaining a clear and effective protection logic.2) 3-pole format: suitable for three-phase installations and simultaneous disconnectionWith its 3P (three-pole) configuration, this model is designed for circuits where coordinated disconnection of the phase conductors is required, typically in 230/400 V three-phase systems or when multipole disconnection is required for operation and maintenance. It is suitable for outgoing circuits supplying equipment such as motors, pumps, ventilation, small machines, or certain distribution boards in professional premises. The modular format makes integration into an electrical distribution board on a DIN rail easier (depending on the enclosure layout), for compliance and clearer organisation of protections.3) Electrical characteristics for everyday use in Europe (50/60 Hz)Rated for an operating voltage of AC 230 to 400 V and a frequency of 50-60 Hz, this RCBO covers most low-voltage configurations encountered in residential, light commercial and small workshop environments. Its 25 A rating must be selected in line with the conductor cross-section, the type of load and the actual operating current: a rating that is too high may reduce the relevance of the circuit protection, while a rating that is too low may cause nuisance tripping. For the best result, sizing is ideally based on the power of the appliances, simultaneity factors and installation conditions.4) C tripping curve: better tolerance to inrush currentThe C curve is recommended when the circuit supplies loads with inrush current at start-up (motors, compressors, pumps, transformers, switch-mode power supplies, etc.). It helps to limit unnecessary interruptions during start-up while maintaining robust protection against abnormal overcurrents. This characteristic makes it a relevant choice for versatile outgoing circuits where you want to avoid equipment start-up causing a trip, while still keeping a fast response in the event of a real fault (sustained overload, solid short circuit, or insulation fault).5) 6 kA breaking capacity and EN 61009 standard reference: a solid basis for the distribution boardWith a breaking capacity of 6 kA, the device is suitable for many final circuits and sub-distribution boards where the prospective short-circuit level remains within usual values. The stated compliance with EN 61009 corresponds to the requirements applicable to residual current circuit breakers with overcurrent protection (RCBO), a point appreciated in renovation, distribution board upgrades or in operating contexts requiring a clear standard reference. For a safe and durable installation, it is advisable to entrust the connection to a qualified person, to follow the terminal markings (line/load, phases), to check tightening and to carry out periodic tests if a test button is present on the model.
