The switch can be installed in any direction. Different installation methods, modular design and wide range of accessories give the product installation flexibility.
Easier to use a special grounding switch can be installed on the floor, and can be rotated 90 degrees.
Saving design time wide series of phase modules, suitable for standard switch cabinet busbar layout.
High performance OT disconnector can be used in harsh application environments.
Tried and tested ABB 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 IEC60947- 3, UL508, UL98 and CSA standards.
Whether it is for demanding motor load disconnecting or simple isolation applications, we offer a market-leading product portfolio of switch-disconnectors ranging from 16 to 4000 Amperes. Thanks to their modular structure, our switches can serve both manual and motorized applications. These devices also help create purpose-built solutions from directly busbar mountable wide phase models to floor mounted earthing switches. All this with the highest level of performance and reliability.
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.
Numerous safety features ABB 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. Reliable in extreme conditions Space saving Safety and protection Safety and protection ABB 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.
