However, the efficiency of against overvoltages cannot be optimally ensured with a single VSP. This is why Legrand recommends combining several VSPs in cascade with different levels, from the first panel as far as the device to be protected (proximity of sensitive devices). An installation will be all the more efficient if, beyond Class I and II VSPs, it comprises proximity VSPs (Class III) on sockets supplying sensitive devices (IT, electronic, etc.).
