Surge protector for photovoltaics TYPE 2 1000VDC SPPVRT2-10-2+PE EP-501966

Photovoltaic installation protection – surge arrester Eaton SPPVRT2-10-2+PE

This type 2 surge arrester, designed for photovoltaic installations with a voltage of up to 1000VDC, is a key element ensuring the safety and long-term operation of your system. It protects against the effects of lightning strikes and network disturbances, safeguarding inverters, photovoltaic modules and other components. The device is mounted on a TH-35 mm DIN rail and occupies 3 modules.

Functionality and technical parameters

The SPPVRT2-10-2+PE surge arrester has been designed with effective DC installation protection in mind. It has the ability to dissipate surge currents with a peak value of up to 20kA, and the maximum discharge current is as high as 40kA. Short-circuit strength at 9kA provides additional safety in the event of a short circuit. Protection level of 3.9kV and 2.5kV L-N guarantees effective protection against overvoltages. Optical signaling informs about the operation of the device, which facilitates diagnosis of any problems.

The arrester offers:

• Effective protection against switching surges and indirect lightning strikes (type 2).
• Adaptation to photovoltaic installations with a voltage of up to 1000VDC.
• Possibility of connecting wires with a cross-section of up to 35mm² (single-/multi-strand) and 25mm² (flexible).
• Protection class IP20 – protection against finger contact and solid objects larger than 12.5 mm.
• Quick identification of the device status thanks to optical signaling.

Application and compatibility

This arrester is ideal for photovoltaic installations in both residential buildings and businesses. It provides reliable protection in various DC network configurations, but is not compatible with IT, TN, TN-C, TN-S or TT and TN-C-S systems. Its versatility makes it an excellent choice for a wide range of users and installers looking for effective protection for their solar energy investments. Additionally, the device has a certificate of conformity with IEC 61643-31:2018, which confirms its high quality and safety of use.
