Residual current circuit breaker with overcurrent protection, 1P+N, C characteristic, 10A, 10kA, 30mA, A, instantaneous DS201 M C10 A30 2CSR275180R1104

Residual Current Circuit Breaker (RCCB) DS201 M C10 A30 is a reliable protection for electrical installations, combining the functions of an overcurrent circuit breaker and a residual current device. The device is designed to protect single-phase circuits against the effects of overloads, short circuits and leakage currents, ensuring the safety of people and equipment.

Protection and Application

This 1P+N circuit breaker with characteristic C is perfect for protecting circuits with a load characteristic with elements with a high inrush current – such as motors, transformers or heating devices. Characteristic C allows for short-term exceeding of the rated current without unnecessary tripping, which is crucial for the correct operation of these devices. At the same time, high sensitivity to leakage currents (30mA, class A) guarantees protection against electric shock. This is especially important in residential premises, offices and other public places.

Technical Characteristics and Construction

The circuit breaker has been designed with easy installation in electrical distribution boards in mind – its width of 2 modules allows for optimal use of space. The rated differential current of 0.03A (30mA) provides effective protection against electric shock upon contact, and the short-circuit breaking capacity of up to 10kA (according to EN 61009) guarantees the safety of the installation in the event of a failure. The circuit breaker is characterized by high resistance to environmental conditions – it can operate at temperatures from -25°C to +55°C. The housing with a degree of protection IP20 protects against touch and ensures safe use. Additionally, the presence of a neutral pole (N) enables full circuit protection.

• Rated current: 10A – suitable for most standard lighting and socket circuits.
• Short-circuit breaking capacity: 10kA – ensures effective disconnection of the power supply in the event of a short circuit.
• Sensitivity: Class A – provides high efficiency in detecting leakage currents of various frequencies, which increases the level of safety.
• Characteristic C: ideal for circuits with devices generating surge currents during start-up (e.g. motors).
• Width: 2 modules – saves space in the distribution board.
• Rated voltage: 240V - standard mains voltage
• Operating temperature: -25°C to +55°C - wide temperature range
