The Surge Protection Device (SPD) category at Roshanex offers protection against voltage spikes from lightning and switching. When a surge hits, an SPD diverts the extra energy to earth, so connected equipment stays safe.

The range features CNC surge protectors for single phase and three phase distribution boards. You can choose a 2P model for homes, or a 4P unit in 40KA and 60KA ratings for larger buildings. Solar installers also fit SPDs on inverter and panel circuits because rooftop systems face lightning risk.

Ask our team which rating suits your board before you order.
