2P 40A AC 220-400V RCBO circuit breaker curve C 6kA EN61009

1) Complete 2-in-1 protection: overload/short-circuit + insulation fault (integrated RCD)This 2P miniature residual current circuit breaker (2PC63A series) combines, in a single compact device, magnetothermal protection against overloads and short circuits as well as residual current protection against leakage currents. It automatically cuts off the power supply as soon as a fault appears, in order to limit risks in residential and small commercial settings: overheating of conductors that can lead to fire, and risk of electrocution linked to current leakage. A practical solution for securing an electrical distribution board: simplified wiring and identification, enhanced protection for people and property.2) 2P format: phase + neutral disconnection for safer isolationThe 2-pole (2P) format is suitable for single-phase installations, with simultaneous disconnection of the phase and neutral. In the event of a fault, separation of the circuit is clearer and reduces the risk that part remains live. Suitable for circuits supplying sockets, lighting, water heaters, air conditioning and small equipment. Maintenance is made easier thanks to more complete circuit isolation, provided safety rules are observed and work is carried out with the power off.3) Electrical characteristics: 40 A, AC 220–400 V, 50/60 HzRated current 40 A, suitable for circuits dedicated to appliances or sub-boards within this range. Compatible with AC 220 to 400 V and frequency 50/60 Hz. The choice of rating must take into account the total power, type of load, conductor cross-section and installation conditions. A rating that is too low may cause tripping, a rating that is too high may delay cable protection: advice from an electrician is recommended.4) C curve and 6 kA breaking capacityThe C curve better tolerates inrush currents (small motors, fans, compressors, pumps, air conditioning) than a B curve, while remaining suitable for common uses. The 6 kA breaking capacity indicates the ability to interrupt high short-circuit currents within the intended limits, helping to protect the installation and reduce damage in the event of a fault.5) EN 61009 compliance and installation adviceComplies with EN 61009 (combined miniature residual current circuit breaker). Recommended for areas at increased risk of insulation fault: kitchen, bathroom, utility room, garage, outdoor sockets, technical rooms, damp environments. DIN rail installation and phase/neutral connection must be carried out correctly (2P disconnection depends on compliant wiring). Carry out periodic tests if a test button is present. In the event of repeated tripping, look for the cause (humidity, faulty appliance, earth leakage, loose connection, overload) rather than increasing the rating. Installation must be entrusted to a qualified professional and carried out with the power off, in accordance with current regulations.
