Overcurrent circuit breaker with residual current device 1+N-pole PKNM-6/1N/C/003-A-MW 236022

Safety and reliability in your electrical installation

The PKNM-6/1N/C/003-A-MW overcurrent circuit breaker with a residual current module is a key element ensuring protection against the effects of overloads and short circuits in electrical circuits. The device combines the functions of an overcurrent and residual current circuit breaker, offering comprehensive protection for both people and equipment. This ensures the installation is safe and the risk of failure is minimized.

This two-pole circuit breaker (1 pole protected + N) with a rated current of 6A, is characterized by a C characteristic, which means it reacts with a delay to short-term current surges – an ideal solution for circuits with receivers generating surge currents, e.g. motors. Additionally, it has a built-in residual current module with A sensitivity (30mA), which effectively detects leakage currents to earth and immediately disconnects the circuit, protecting against electric shock.

Application and benefits:

• Protection against overload and short circuit: Provides effective protection of electrical wires and devices against damage caused by excessive load or short circuit.
• Electric shock protection: The built-in residual current module minimizes the risk of electric shock by quickly detecting leakage currents to earth.
• Versatility: Suitable for use in various types of electrical installations, both in residential and commercial buildings.
• Easy installation: Compact dimensions (2 modules wide) make it easy to install in a distribution board.
• High reliability: Made of high-quality materials, guarantees long-lasting and trouble-free operation.
• Rated breaking capacity 10kA: Ensures effective disconnection of the circuit in the event of a short circuit with high energy.

Construction and technical parameters:

The circuit breaker has been designed with safety and functionality in mind. It has energy limitation class 3 and protection degree IP20, which means protection against touching with a finger and solid bodies larger than 12.5 mm. Adapted to work in ambient temperature from -25°C to 40°C. The possibility of connecting wires with a cross-section from 1 mm² to 25 mm² (solid or stranded) provides flexibility during installation. The rated insulation voltage Ui is 440V and the rated impulse withstand voltage Uimp is 4kV, which guarantees safety even in difficult operating conditions. At the same time, the disconnectable N pole increases safety during maintenance and repair of the electrical installation.
