Overvoltage arrester for DC installations
Modern photovoltaic (PV) and direct current (DC) power systems are increasingly exposed to the effects of atmospheric and switching surges. In order to ensure reliable protection of equipment and electrical infrastructure, it becomes crucial to use surge protective devices (SPDs), adapted to system parameters and normative requirements.
Relpol S.A., known for manufacturing protection devices, offers a series of professional RSP-type surge arresters dedicated to PV/DC applications with voltages from 600 VDC to 1500 VDC. All products in this line meet the requirements of the IEC 61643-31 standard, are tested for reliability and safety, and their design enables quick installation and efficient replacement.

Key features of RSP arresters for DC installations
Protection class
Relpol RSP series arresters are classified as Class I+II, II (Type T1+T2 and T2), which means the ability to protect against both direct lightning surges and surges of industrial origin.
Pluggable design
All models are equipped with a pluggable design to allow rapid replacement of modules without having to disconnect the installation.
Compliance with standards
The products are certified by CE and TUV bodies and comply with IEC 61643-31, which guarantees safe use and compatibility with international quality systems.
