Surge arrester type T2, 3-pole, 1000 V DC, Imax: 40kA, In: 20kA (8/20) RSP-T2-DC/3P 2617147

DC Installation Protection – Reliability and Safety

The RSP-T2-DC/3P surge protector is a key element in protecting photovoltaic installations and other DC systems from the effects of lightning strikes and overvoltages. This Class T2, three-pole device is designed to operate in systems with voltages up to 1000V DC and effectively protects sensitive components from damage. Its function is to divert excess energy to ground, minimizing the risk of failure and ensuring continuous operation of the installation.

Design and Application

This surge protector is used in the construction of safe and reliable photovoltaic installations, electric vehicle chargers, and other direct current powered systems. Mounting on a 35 mm DIN rail facilitates integration with existing electrical infrastructure. The three-pole design provides comprehensive protection for the entire circuit. Optical signaling indicates when the surge protector has activated, allowing for quick identification of potential problems.

Performance and Parameters

The rated discharge current (In) of 20kA (8/20) and the maximum discharge current (Imax) of 40kA guarantee effective protection even with strong overvoltages. The maximum continuous operating voltage (Uc) of 1000V DC makes it an ideal solution for most standard photovoltaic installations. Thanks to the possibility of connecting cables with a cross-section of up to 35mm², these surge protectors are compatible with various types of cabling. It is worth noting the universality – the surge protectors work with TT-, TN-S and TN-C-S network systems. The lack of a remote signaling contact simplifies the design and reduces installation costs while maintaining basic functionality.
