Residual Current Circuit Breakers – Protection and Safety of Installations

This residual current circuit breaker, designated as DS201 M B6 A30, is a reliable device used for comprehensive protection of electrical circuits. It combines the functions of an overcurrent and residual current circuit breaker, providing effective protection against overloads, short circuits, and electric shock. It is a key element of every modern electrical installation, both in residential and commercial buildings.

The device is designed for mounting on a DIN rail and is characterized by a compact design – it occupies only two modules. This makes it easy to integrate with existing distribution boards. Made of high-quality materials, it guarantees long-lasting and trouble-free operation.

Construction features and operating parameters

The DS201 M B6 A30 circuit breaker has been designed with safety and functionality in mind. Characteristic B provides a quick response to short-circuit currents, minimizing the risk of damage to the installation and equipment. The rated residual current of 30mA provides a high level of protection for people against electric shock. Additionally, the presence of a neutral pole (N) increases safety.

This circuit breaker is perfect for protecting circuits with lower loads, such as lighting or sockets in residential premises, thanks to the rated current of 6A. Its breaking capacity of 10kA effectively disconnects the circuit in the event of a short circuit, protecting against serious damage. Sensitivity class A is dedicated to detecting sinusoidal leakage currents, typical of most electrical appliances. The standard rated voltage of 240V ensures compatibility with most installations in Poland. Instantaneous tripping time guarantees a quick response to overloads and short circuits. The compact width of 2 modules saves space in the distribution board, and the operating temperature range from -25°C to +55°C allows use in various environmental conditions.

This circuit breaker meets strict safety standards (energy limitation class 3, surge category 3, pollution degree 2), which confirms its high quality and reliability. The cross-section of the connected multi-wire cable from 0.75 mm² to 16 mm² provides flexibility in choosing cables tailored to specific installation needs.
