Overcurrent circuit breaker with residual current device 1+N-pole PKNM-32/1N/C/003-MW 236305

Safety and Reliability in Your Electrical Installation

This overcurrent circuit breaker with a residual current device (RCD) is a key element in protecting your electrical installation, safeguarding both people and equipment. Model PKNM-32/1N/C/003-MW combines the functions of an overcurrent and residual current breaker, providing comprehensive protection against the effects of short circuits, overloads, and electric shock. This is particularly important in residential premises, offices, and other public buildings.

Functionality and Technical Parameters

This breaker is characterized by a rated current of 32A and a C characteristic, which means it allows for short-term overloads without unnecessary tripping – an ideal solution for devices with motors or other elements generating high starting currents. Additionally, the built-in residual current device with a sensitivity of 30mA (AC) provides protection against electric shock by quickly disconnecting the circuit in the event of a leakage current to earth. The rated short-circuit breaking capacity of 10kA guarantees effective disconnection of the circuit in the event of a short circuit.

The 1+N pole design allows for simultaneous disconnection of the phase and neutral, which increases safety. A width of 2 modules simplifies installation in standard distribution boards. The breaker meets the requirements of EN 61009 standard, confirming its high quality and reliability.

• Versatile application: ideal for protecting lighting circuits, socket circuits, and electrical appliances.
• Overload protection: C characteristic provides resistance to short-term current surges, typical of devices with motors.
• Electric shock protection: 30mA (AC) sensitivity ensures quick disconnection of the circuit in the event of a leakage current.
• High short-circuit breaking capacity: 10kA guarantees effective disconnection of the circuit in the event of a short circuit.
• Compact dimensions: 2 module width simplifies installation in standard distribution boards.
• Safety confirmed by standards: compliance with EN 61009 ensures high quality and reliability of the product.
• Operating temperature range: from -25°C to 40°C enables operation in various environmental conditions.
• Wire cross-section: possibility of connecting solid and stranded wires with a cross-section from 1 to 25 mm².

Installation and Operation

Installation of the breaker is simple and intuitive, and its compact dimensions allow for easy placement in a standard distribution board. The breaker is designed to operate at a rated voltage of 230V and a frequency of 50Hz. The IP20 degree of protection provides protection against finger contact, but does not protect against the effects of water or dust – therefore, avoid installation in damp or dusty rooms. Remember to select the correct wire cross-section (1-25mm²) to ensure optimal device operation.
