VL-SPD-01 — Class C Surge Protective Device, AC 230/400V
The VL-SPD-01 series provides reliable lightning and overvoltage protection for AC 50/60Hz, 230/400V electrical systems.
Featuring a built-in, non-replaceable disconnector, the device automatically isolates itself from the electrical network in the event of overcurrent, overvoltage, or internal failure.
The status indication window clearly changes from green to red, signaling device failure and the need for replacement.
