Surge Protection Device (SPD)
The ultimate defense against transient over-voltages and lightning surges. Protect your PLC, Computers, and Expensive Machinery from instant burnout.
Why Install an SPD?
Lightning Rods protect the building structure, but they cannot stop the massive voltage surge traveling through wires. Earthingz SPDs act as a barrier, diverting excess voltage to the ground in nanoseconds.
We offer SPDs for Main Distribution Boards (Type 1) and Sub-Distribution Boards (Type 2). They come with replaceable cartridges and a visual flag (Green/Red) to indicate device health.
