Essential protection Overvoltages due to lightning are responsible for 25% to 40% of the damage caused to equipment. If we include transient overvoltages with other origins, this adds up to 60% of electrical damage that can be prevented by installing SPDs. The whole Legrand SPD range conforms to the EN and IEC 61643-11 standards. Safety & adaptability 1P+N and 3P+N SPDs with dedicated neutral pole protection are used to dissipate common and differential mode overvoltages that are likely to happen in installations with a TT and TNS system when there is a lightning strike. In order to adapt to customs in different countries, they are available with neutral on the right-hand or neutral on the left-hand side. Status indication A cassette status indicator signals whether the SPD is working (green) or not working (orange): this makes it much easier to maintain the installation! Ergonomics The improved ergonomics of SPDs make it easy to replace cassettes using the extraction handles. Design & marking The new design of SPDs, consistent with Legrand modular devices, benefits from dedicated marking. Once installed in the board, the product is therefore easier and quicker to identify!
