The Eaton PKNM-6/1N/C/003 is a high-quality residual current circuit breaker with overcurrent protection (RCBO), engineered to provide comprehensive electrical safety in a compact 2-pole design. This device integrates both short-circuit and overload protection with residual current detection, ensuring that electrical circuits are shielded from dangerous faults. It is specifically designed to handle a rated current of 6A and features a C-type tripping characteristic, making it suitable for circuits with moderate inrush currents. With a sensitivity of 30mA, it effectively detects AC-type leakage currents to prevent electrical hazards.
Advantages
This RCBO offers a space-saving solution by combining two essential protective functions into a single modular unit, which simplifies installation and reduces the space required in distribution boards. The robust construction ensures reliable performance in various residential and commercial environments, providing consistent protection against both overcurrent conditions and ground faults. Its design facilitates easy mounting and integration into standard electrical systems, offering a dependable safety mechanism that meets professional standards for electrical installations.
Suitable for
- Residential electrical distribution boards
- Commercial office lighting and power circuits
- Protection of final circuits against overloads and short circuits
- Personnel protection against indirect contact with electrical equipment
When it may not be suitable
This device is designed specifically for AC-type leakage currents and may not be suitable for installations where DC components are present in the leakage current, such as those involving certain types of frequency converters or electric vehicle charging stations. It is also not intended for use in high-current industrial machinery that exceeds the 6A rated capacity.
Key specifications
- Rated current: 6A
- Tripping characteristic: C-curve
- Sensitivity: 30mA
- Leakage current type: AC
- Poles: 2P (1P+N)
How to use
The Eaton PKNM-6/1N/C/003 should be installed by a qualified electrician in accordance with local electrical regulations. It is designed for mounting onto a standard DIN rail within a distribution enclosure. Ensure that the supply cables are correctly connected to the input terminals and that the load circuit is connected to the output terminals, observing the correct polarity for the neutral conductor. After installation, the device should be tested using the integrated test button to verify its mechanical operation and tripping functionality.
What to consider before purchase
- Verify that the 6A rated current is appropriate for the specific load of the circuit.
- Ensure the installation environment is compatible with AC-type residual current protection.
- Check the available space in your distribution board for a 2-pole modular device.
- Confirm that the C-curve tripping characteristic matches the startup requirements of your connected appliances.
Usage recommendations
Regularly test the device using the test button at least twice a year to ensure the internal mechanism remains functional and provides reliable protection for your electrical system.
