Switch-disconnectors range for PV installations 1500 V DC

Photovoltaic will grow by 13% per year globally until 2030 with increasing needs in terms of safety and security to ensure proper operation and maintenance. Our goal: to accompany the development of utility scale PV installations with innovative, efficient and everlasting technologies.

This approach is precisely what has led us to acquire precise expertise in the development of switching and protection solutions for DC. Among them, our switch-disconnectors for photovoltaic installations 1500  V DC (combiner boxes and inverters), stand out. Manufactured with high safety self- extinguishing materials, our full product range provides an excellent level of electrical insulation, low smoke emissions and high resistance to electromechanical stress.
