Earth leakage switches | Legrand Lietuva

We offer two versions


This range of differential switches is particularly suitable for domestic installations thanks to its compliance with thermal stress (3000 A - 22.5 kA²s). 


This range of earth leakage switches is mainly used in commercial and industrial buildings. In addition, these products are equipped with rear sockets that allow them to be clipped (power supply) to our HX³ plug optimised distribution systems.
