RS PRO Type 1 + 2 Unipolar Surge Protector


The RS PRO surge protectors are heavy-duty Type 1+2 devices specifically designed to protect electrical installation entry points. They provide robust protection for bi-phase, 3-phase, and 3-phase + neutral networks, either in common mode or both common and differential modes. Built with advanced multilayer varistor technology, these protectors ensure optimal performance in low-voltage networks without generating follow-on currents. For easy installation, they are DIN rail-mounted and feature a dual connection for the active conductor, offering an optimised and reliable network connection.
