Switch-disconnectors 16 to 4000 Amperes
We offers switch-disconnectors suitable for diverse applications such as machinery, power distribution, switchboards, motor control centers or photovoltaic installations. These devices are globally available and always supported by our skilled and dedicated worldwide service network. We also offers a complete range of enclosed switch-disconnectors in various enclosure materials.
Reliable in extreme conditions:
We switch-disconnectors are designed, built and tested for the best possible performance. They are designed to be virtually maintenance free across their entire extended lifespan and offer reliable performance in any and all possible circumstances. Durability has been ensured by testing switches against the IEC609473, UL508, UL98 and CSA standards.
Space saving:
All our switches have been designed for easy and cost-efficient installation,
maintenance and use. Their modular design and smaller dimensions enable installation into even the smallest enclosures saving precious space and significantly reducing material, handling and installation costs. The simple design also makes use easy, even without previous experience or training.
Safety and protection:
We switch-disconnectors come equipped with a comprehensive range of inbuilt safety features. All motorized switches can also be operated manually in emergency situations, but can also be padlocked when the handle is removed to prevent unwanted manual or remote operations or enable safe maintenance work.
