RCD/MCB DS201 C10 AC30 – protection for installations and people

This RCD/MCB is a key element ensuring safety in every electrical installation. Designed to protect against the effects of short circuits, overloads and electric shock, it combines the functions of an overcurrent and residual current device. The DS201 C10 AC30 model, with a rated current of 10A and C characteristic, is perfect for both lighting and socket circuits, as well as for protecting devices with higher power consumption.

Construction and application

This circuit breaker is a single-pole device with a connected neutral pole (1P+N), which means it protects one phase and neutral circuit. The C characteristic provides a delayed tripping response to short-term overloads, which is particularly important when connecting receivers with motors or transformers – avoiding unnecessary tripping of the circuit when starting such devices. A sensitivity of 30mA to differential current guarantees a quick response in the event of a current leakage to earth, minimizing the risk of electric shock. Mounting is on a DIN rail, which simplifies and speeds up installation.

Key features and benefits

• Versatile application: ideal for residential, commercial and industrial installations.
• Overload and short-circuit protection: provides comprehensive protection for the electrical installation.
• Protection against electric shock: 30mA sensitivity guarantees a quick response to earth leakage currents.
• C characteristic: allows for trouble-free starting of devices with motors and transformers without unnecessary tripping of the circuit breaker.
• Compact dimensions: 2 module width saves space in the distribution board.
• Rated breaking capacity 6kA: ensures effective disconnection of the circuit in the event of a short circuit.
• Cross-section of connectable multi-wire conductor 0.75…16 mm²: allows connection of wires of different thicknesses.
• Rated voltage 240V and frequency 50/60Hz: compatible with most standard electrical installations in Poland.

Technical parameters in practice

Breaking capacity of 6kA means that the circuit breaker is able to safely interrupt a short-circuit current of 6000 amps – this is important for ensuring the safety of the entire installation in the event of serious failures. Operating temperature from -25°C to +55°C means it can be used in various environmental conditions. Energy limitation class 3 indicates high resistance to the effects of electric arc energy generated during short-circuit extinguishing – this translates to longer device life and increased safety of use. Protection class IP20 provides protection against accidental contact, but does not protect against the effects of water or dust – remember to install in a dry and well-ventilated place.
