Installation switches Ex9IP find their application in photovoltaic and general DC systems, where is required only switch off function. They are offered in versions with rated current up to 63A and and rated voltage to 1000 V DC.
These isolators can be supplemented with a wide range of accessories identical with circuit breakers Ex9B (except Ex9LE RCD add-on blocks). E.g. undervoltage release UVT can be used for safety disconnection of panels from the rest of the installation.
