3P 50A RCBO type C 6kA 230-400V EN61009

1) Complete 2‑in‑1 protection for three-phase networksThis 3P 50 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 / earth leakage (residual current function). It is designed to secure installations more effectively where continuity of service and protection of people are essential. In the event of a fault, it quickly interrupts the power supply in order to limit the risks of electric shock and electrical fire outbreak. Its 3-pole (3P) architecture allows simultaneous protection of a three-phase circuit and provides a compact solution, particularly appreciated in small and medium-sized electrical panels.2) Main characteristics suited to low-voltage installations UENumber of poles: 3P (three-phase), simultaneous protection of the three phasesRated current: 50 A, suitable for common power outgoing ways in final distribution (it is recommended to keep a margin and avoid prolonged operation at full load)Operating voltage: AC 230–400 V, compatible with the most common single-phase/three-phase low-voltage networksFrequency: 50/60 Hz, for broad compatibility depending on the equipment and installation environmentBreaking capacity: 6 kA, a standard level for many commercial and light industrial applications (to be validated according to the prospective short-circuit current of the site)Tripping curve: type C, better suited to loads with inrush current (motors, pumps, fans, compressors, etc.), limiting nuisance tripping while ensuring protectionStandard reference: EN/IEC 61009, European standard associated with devices combining circuit breaker and residual current protection3) Space saving and simplified wiring in the panelThe integration of circuit breaker + residual current functions in a miniature format reduces the footprint compared with combining several devices (circuit breaker + separate residual current device). Result: cleaner layout, more direct wiring, easier identification and faster maintenance work. This approach helps improve the overall reliability of distribution and the readability of the panel, particularly during a cabinet refurbishment or the addition of a three-phase outgoing way. It is a relevant solution when the available space is limited or when seeking to limit the complexity of assemblies.4) Typical uses: light industry, technical commercial premises and motor-driven equipmentThis 3P 50 A model is particularly suitable for environments where three-phase circuits and electromechanical loads are found: workshops and power circuits, pumping stations, ventilation units, compressors, small production machines, secondary distribution cabinets, plant rooms, professional kitchens, damp areas or areas with many metal frames. In these contexts, the C curve provides a good compromise between inrush current tolerance and protection, while the residual current function helps reduce the risks linked to insulation faults likely to appear with the age of cables, humidity, vibrations or mechanical stresses.5) Installation recommendations (good practice) and safetyTo ensure correct operation, it is advisable to have this residual current circuit breaker installed by a qualified electrician, in accordance with good practice and local requirements (cable sizing, torque tightening, verification of network voltage, earth continuity, etc.). On a 50 A outgoing way, the cross-section of the conductors and the quality of the terminations are crucial in order to avoid any overheating due to poor contact. For loads close to the rated current, allow a sizing margin in order to limit operating temperature and tripping. Finally, as with any residual current device, periodic checking (test and visual/thermal inspection of the connection) helps maintain a constant level of safety over time.
