MCB circuit breaker 3P 16A curve C 6kA without RCD

1) Essential protection for three-phase circuits: overload + short-circuit (without residual current protection)This 3P 16 A MCB miniature circuit breaker is designed to provide basic protection for electrical installations by tripping automatically in the event of prolonged overload (overheating of conductors, premature ageing of cables) and short-circuit (sudden fault with a sharp rise in current). Model without residual current protection: it does not detect earth leakage currents and therefore does not directly protect people against electric shock. For areas with increased risk (wet rooms, outdoors, portable tool circuits, damp environments), it is recommended to add a suitable RCD/RCCB/RCBO, upstream or downstream depending on the distribution board architecture.Characteristics compliant with European practices (EN 60898‑1)Designed for domestic and similar installations, this circuit breaker complies with EN 60898‑1, commonly required in distribution boards in Europe. It operates on AC 230/400 V on a 50/60 Hz network, compatible with common single-phase/three-phase configurations (depending on the wiring diagram). Its 6 kA breaking capacity is suitable for most residential environments and many small commercial premises. Where a higher prospective short-circuit current is present (proximity to a transformer, certain industrial installations), an assessment of the Ik and a higher breaking capacity may be required.3 poles (3P): simultaneous disconnection of three conductorsThe 3P configuration allows three phases or three conductors requiring common disconnection to be isolated and protected, which is practical for three-phase circuits and certain outgoing ways where it is desirable to isolate a group of lines in a single operation. This makes maintenance and fault isolation of an outgoing circuit easier, while maintaining a clear board logic. Ideal for a domestic distribution board with three-phase equipment, a small commercial enclosure, or an equipment control cabinet.C tripping curve: start-up stability, controlled protectionThe C curve is a versatile choice widely used, particularly when the circuit supplies loads that may present inrush current (small motors, fans, power supplies, certain technical equipment). It reduces the risk of nuisance tripping on start-up while maintaining effective protection against overcurrents. The 16 A rating must be selected in line with the conductor cross-section, installation method and power of the appliances: a circuit breaker also protects the cable, not only the equipment.Typical applications and integration advice for the distribution boardRecommended for: three-phase outgoing circuits, technical equipment circuits, small distribution enclosures, workshop control cabinets, board subdivisions requiring reliable overload/short-circuit protection. For a compliant and durable installation: correct tightening of terminals (avoid overheating through poor contact), circuit identification, addition of residual current protection where protection of persons is required (kitchens, bathrooms, outdoors, sockets dedicated to tools).
