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.
Every need has its solution:
- SPDs without short circuit protection (T1+T2 and T2)
- SPDs with integrated short circuit protection with MCBs (T2)
- SPDs with integrated short circuit protection with fuses (T2+T3)
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.
A cassette status indicator signals whether the SPD is working (green) or not working (orange): this makes it much easier to maintain the installation!
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!
Solutions for all types of installation and all levels of risk.
