CNC YCS6-C AC Surge Protection Device SPD 4 Pole 385V – 20-40kA, 40-60kA, 60-80kA

Dependable 3-Phase Surge Protection by CNC Electric

The CNC YCS6-C AC Surge Protection Device protects three-phase (L1, L2, L3 + N) systems from lightning strikes and switching surges. Mounted in your distribution board, it diverts dangerous surge energy safely to earth, protecting solar inverters, motors, machinery, and sensitive electronics from costly damage.
