Miniature circuit breaker 4P 20A C curve 6kA without residual current device

1) Reliable circuit protection (without residual current protection)This 4-pole 20 A miniature circuit breaker (MCB) is designed to protect an electrical installation against overloads and short circuits. It quickly cuts off the power supply in the event of a fault in order to limit the risks of overheating, damage to appliances or fire. Please note: “without residual current protection” means it does not protect against current leakage (insulation fault) or electric shock. For personal protection (kitchen, bathroom, outdoor sockets, etc.), it is recommended to add an upstream residual current device of the RCD/RCCB/RCBO type suitable for the consumer unit.2) 4P format: ideal for three-phase with neutral and simultaneous disconnectionThe 4P (4-pole) configuration allows four conductors to be controlled and protected in a single operation. It is particularly suitable for three-phase installations to simultaneously disconnect the three phases + the neutral, or where more complete isolation is required during work. In the event of tripping, the entire circuit is isolated, which improves diagnostic clarity and safety during inspection operations in a consumer unit or cabinet.3) Electrical characteristics suited to European networksAC operating voltage 230–400 V, frequency 50/60 Hz: compatible with most low-voltage networks in Europe (domestic, small commercial premises, workshops, three-phase distribution board outgoing circuits). Rated current 20 A: to limit overheating and improve service life, it is advisable to keep an operating margin (often around 80% depending on the load, temperature, wiring density and cabinet ventilation).4) C tripping curve: good compromise for common loads and motorsThe C curve offers good tolerance to inrush currents at start-up while ensuring rapid disconnection in the event of a fault. It is suitable for small motors, fans, pumps, low-power compressors, switch-mode power supplies, as well as resistive loads (lighting, heating). If inrush currents are very high, another curve may be more suitable depending on the installation study.5) 6 kA breaking capacity, EN 60898-1 compliance: consumer unit/cabinet use6 kA breaking capacity: standard level for the protection of final circuits (housing, shops, commercial premises) according to the short-circuit current available on site. Complies with EN 60898-1, a common standard for domestic and similar circuit breakers, making integration into a consumer unit easier. Typical mounting on DIN rail. In the event of tripping, it is recommended to look for the cause (overload, wiring, faulty appliance, loose terminal) rather than repeatedly resetting it.
