## Long description

The Eaton PKZ-SOL20 is a specialized string circuit breaker engineered specifically for the protection of photovoltaic installations. This device serves as a robust, fuseless alternative for safeguarding solar modules against short-circuit currents. With a rated current of 20 A and a rated voltage of 900 V, it is designed to maintain the integrity of DC circuits within solar power systems, ensuring both safety and operational efficiency.
Advantages
This circuit breaker offers a significant advantage through its variable tripping range, which allows for precise adjustment to the actual short-circuit current of a specific string. By eliminating the need for traditional fuses, it simplifies maintenance and increases the reliability of the system. The compact design facilitates professional electrical integration into various renewable energy setups, while the option to include a delayed undervoltage release enables remote switching capabilities, which is a critical feature for emergency response scenarios such as fire brigade access.
Suitable for
Photovoltaic module protection
DC circuit safeguarding in solar power systems
Renewable energy installations requiring fuseless short-circuit protection
Systems requiring remote switching capabilities via optional accessories
This device may not be suitable for AC electrical systems, as it is specifically designed for DC photovoltaic applications. It is also not intended for environments requiring high ingress protection, as it carries an IP20 rating, meaning it must be installed within a suitable enclosure to protect against dust and moisture.
Key specifications
Rated current: 20 A
Rated voltage: 900 V
Power dissipation: 4.8 W
Protection rating: IP20
Technology: Fuseless short-circuit protection
The Eaton PKZ-SOL20 should be installed by a qualified professional in accordance with local electrical regulations. It is designed for integration into a distribution board or enclosure suitable for DC solar components. Ensure that the tripping range is correctly adjusted to match the specific short-circuit current requirements of your solar string to guarantee optimal protection.
What to consider before purchase
Verify that the 20 A current rating matches your string requirements
Ensure the 900 V voltage rating is compatible with your PV array
Confirm that the IP20 rating is sufficient for your installation environment or plan for an additional protective enclosure
Check if remote switching functionality is required and if the optional undervoltage release is needed
Usage recommendations
Always perform a thorough inspection of the electrical connections after installation and ensure that the device is properly calibrated to the specific string current to prevent nuisance tripping or inadequate protection.
