3P+N Residual Current Circuit Breaker 32A Type C 6kA EN61009

1) 2-in-1 protection for demanding three-phase networks (3P+N)This modular 3P+N C32A RCBO combines in a single device protection against overloads and short circuits (circuit breaker function) and residual current protection (earth leakage). It is designed to secure circuits where good continuity of service is expected, while greatly reducing the risks of electrocution and fire of electrical origin. Ideal in distribution boards for workshops, small shops, technical rooms/racks, floor distribution boards, power supply circuits for three-phase + neutral equipment and dedicated outgoing ways for machines or apparatus requiring a complete protection logic. In the event of an insulation fault, moisture, cable ageing or an anomaly on a device, tripping is rapid in order to limit the consequences for people and installations.2) 3 phases + neutral configuration, suitable for European 230/400 V standardsThe 3P+N version is suitable for three-phase 4-wire installations: L1/L2/L3 + N, typical of 230/400 V networks. Its AC 230-400 V operating range covers the majority of tertiary and light industrial applications, including 400 V distributions for motors and equipment, as well as outgoing ways requiring the neutral. 50-60 Hz compatibility makes integration easier on many sites (50 Hz European networks, imported machines, specific equipment). This architecture is particularly relevant when several three-phase loads coexist with single-phase auxiliaries, or when the neutral must be monitored and disconnected consistently with the phases according to the board architecture.3) 32 A rating and C curve: a good compromise for loads with inrush currentWith a rated current of 32 A (C32A), this model is intended for common outgoing ways in three-phase distribution (sub-distribution boards, machine circuits, equipment lines). The C tripping curve is recommended when the loads have a starting current or transient inrush: small three-phase motors, fans, pumps, compressors, switch-mode power supplies, transformers, mixed socket/lighting circuits or controls with coils. Compared with a B curve, the C curve limits nuisance tripping at start-up while maintaining effective protection against overcurrents. For highly inertial motors or very severe starts, sizing must remain in accordance with installation calculations (cross-section, length, Ik, starting method).4) 6 kA breaking capacity: a practical level for many final distribution boardsThe 6 kA breaking capacity indicates the device's ability to interrupt a significant short-circuit current under standardised conditions. This level is frequently used on final outgoing ways and local distribution boards (offices, shops, workshops, technical rooms) where the prospective short-circuit current remains within a compatible range. For installations close to a transformer, main LV switchboards, or environments where the Ik may be higher, it is recommended to have the prospective short-circuit current checked by a professional and to adapt the breaking capacity accordingly in order to ensure satisfactory coordination and selectivity.5) EN 61009 compliance and installation and maintenance recommendationsCompliant with EN 61009 (a common reference standard for RCBOs), this product integrates more easily into a selection, acceptance and maintenance approach according to Euro-compatible practices. For reliable use: installation on a DIN rail by a qualified electrician, clear identification of the L1/L2/L3/N conductors, tightening to torque and checking for overheating (poor tightening: risk of heating and deterioration). It is advisable to carry out a residual current operating test regularly via the test button (according to the site's usual intervals, particularly in damp, dusty, vibrating environments or those subject to large temperature variations). In a board, the device can serve as outgoing way protection or dedicated protection for risk areas (outdoors, damp rooms, mobile equipment), in coordination with the main switch, upstream protection and, if necessary, a surge arrester for a more complete protection architecture.
