Overcurrent circuit breaker with residual current device 1+N-pole PKNM-10/1N/B/003-A-MW 236072

Safety and reliability in your electrical installation

The RCD/MCB PKNM-10/1N/B/003-A-MW is a key element in protecting electrical circuits, combining the functions of an overcurrent circuit breaker and a residual current device. It provides comprehensive protection against the effects of overloads, short circuits and electric shock, making it an ideal solution for both professional installers and end users.

Functionality and application

This two-pole (1+N) circuit breaker with a rated current of 10A and B characteristic effectively protects circuits against the effects of sudden current surges, typical of devices with induction motors or transformers. Characteristic B means that the circuit breaker reacts quickly to a short circuit, but is more tolerant to short-term overloads – which is important when connecting receivers with high inrush current. In addition, the built-in residual current module with a sensitivity of 30mA (0.03A) provides personal protection against electric shock. Use in circuits with a voltage of 230V guarantees compatibility with most standard electrical installations.

Construction and installation

The PKNM-10/1N/B/003-A-MW circuit breaker occupies 2 module widths, making it easy to install in electrical distribution boards. The IP20 degree of protection provides basic protection against accidental contact. The possibility of connecting solid and stranded wires with a cross-section from 1 to 25 mm² provides flexibility during installation. The circuit breaker is designed to operate at temperatures from -25°C to 40°C, allowing it to be used in various environmental conditions. At the same time, the disconnectable N pole increases safety during maintenance and repair of the installation. The rated short-circuit breaking capacity Icn at 10kA ensures effective protection against the effects of serious failures.
