2P 16A miniature circuit breaker C curve 6kA 230-400V without RCD

1) Reliable overcurrent protection (without residual current protection): This 2P 16 A miniature circuit breaker (MCB) is designed to provide protection against overloads and short circuits in low-voltage installations. It cuts off the power supply as soon as a dangerous overcurrent appears, limiting conductor heating, insulation ageing and the risk of electrical incidents. Please note: this is a version without residual current protection (no earth leakage detection). It therefore does not replace an RCD/RCCB for protecting people against electric shock. For sensitive circuits (bathroom, kitchen, outdoors, water heater, accessible sockets, appliances in damp environments), it is recommended to add an upstream residual current device or to opt for an RCBO depending on the board configuration.2) 2-pole configuration: simultaneous disconnection for greater maintenance safety: The 2P (double-pole) format allows the simultaneous disconnection of two conductors (often live + neutral, or two lives depending on the installation). This feature is valued in homes and small commercial premises when a clearer isolation of the circuit is required during work, troubleshooting or lockout. In practice, this makes it easier to isolate an outgoing circuit (lighting, sockets, small equipment) and improves maintenance convenience in a domestic consumer unit, a small commercial enclosure or an equipment control enclosure.3) 16 A rating: a standard for many domestic outgoing circuits and small applications: The 16 A rated current corresponds to a very common rating for socket circuits, circuits dedicated to small appliances, certain mixed outgoing circuits, or control circuits in technical cabinets. The protection logic is simple: in the event of a prolonged excess over the permissible current, the circuit breaker trips according to its thermal characteristic (overload); in the event of a short circuit, it trips much more quickly via the magnetic part, in order to reduce fault energy as much as possible. However, the choice of rating must remain consistent with the conductor cross-section and the power actually drawn: a circuit breaker that is too “large” in relation to the cable may allow the cable to heat up without immediate tripping.4) C curve: tolerance to inrush currents, versatile use: The C tripping curve is a very common choice because it offers good tolerance to inrush currents (starting of small motors, circulation pumps, fans, transformers, switched-mode power supplies, certain equipment with capacitors). It limits nuisance tripping compared with a B curve, while remaining responsive in a short-circuit situation. This makes it a good all-round solution for many circuits in homes, small shops and technical equipment, particularly when the nature of the loads is not strictly resistive or perfectly stable.5) Network compatibility and European compliance: 230/400 V – 50/60 Hz, EN 60898-1, 6 kA breaking capacity: Designed for AC 230/400 V networks and a frequency of 50–60 Hz, this circuit breaker meets residential and similar-use applications. It is stated to comply with EN 60898-1, the reference standard for miniature circuit breakers intended for domestic/light commercial installations, providing recognised performance and safety requirements. Its 6 kA breaking capacity is suitable for the majority of standard installations (homes, small commercial premises, sub-distribution boards). For sites close to a transformer or likely to present a higher short-circuit current (certain industrial installations), it may be relevant to consider a higher breaking capacity depending on the assessment of the installation point.
