## Summary description

The Relpol RSP-T1T2-DC is a high-performance surge protection device designed for photovoltaic systems. It features a 3-pole configuration with a maximum discharge current of 50kA and an operating voltage of 1000V DC. This T1+T2 class arrester provides reliable protection against atmospheric and switching overvoltages, ensuring the safety and longevity of solar power installations and connected electrical equipment.

## Long description

The Relpol RSP-T1T2-DC is a robust surge protection device specifically engineered to safeguard photovoltaic systems from electrical transients. By combining Type 1 and Type 2 protection classes, this 3-pole arrester effectively manages high-energy surges caused by atmospheric discharges or switching operations within solar power installations. Its design ensures that sensitive components, such as inverters and solar panels, remain protected against voltage spikes, thereby enhancing the overall reliability and operational lifespan of the system.
Advantages
This surge protection device offers a high discharge capacity, capable of handling up to 50kA, which provides a significant safety margin for demanding solar energy environments. The integration of T1 and T2 protection levels in a single unit simplifies installation while maintaining comprehensive coverage against both direct and indirect lightning strikes. Its 1000V DC rating makes it highly compatible with modern high-voltage solar strings, ensuring consistent performance and stability under varying environmental conditions.
Suitable for
Photovoltaic power systems and solar energy installations
Protection of DC-side equipment including inverters and charge controllers
Industrial and residential solar power setups requiring high-capacity surge suppression
When it may not be suitable
This device is specifically designed for DC circuits in photovoltaic systems and should not be used in AC power distribution networks. It is also not intended for applications where the operating voltage exceeds the 1000V DC threshold, as this could lead to device failure or safety hazards.
Key specifications
Protection class: T1+T2
Operating voltage: 1000V DC
Maximum discharge current: 50kA
Configuration: 3-pole
How to use
The device should be installed by a qualified professional in accordance with local electrical regulations. It is typically mounted on a standard DIN rail within the DC distribution box, positioned between the solar array and the inverter. Ensure that the wiring connections are secure and that the grounding path is properly established to allow the device to divert surge energy effectively. Regular inspection of the status indicator is necessary to confirm the device remains in an operational state.
What to consider before purchase
Verify that the maximum system voltage of your solar array does not exceed 1000V DC
Ensure the installation environment allows for proper DIN rail mounting
Confirm that the local electrical standards permit the use of T1+T2 class arresters for your specific system configuration
Usage recommendations
Regularly check the visual status indicator on the device to ensure it has not reached the end of its service life. If the indicator shows that the protection module has been triggered, the unit must be replaced immediately to maintain system safety.
