Reliable in extreme conditions

 

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.

 

Space saving

 

All our switches have been designed for easy and cost-efficient installation, maintenance and use. The modular design enables 2-, 3- and 4-pole installation with different position of the switching mechanism to suit your needs and spacial requirements. The devices can be optimized in relation to busbar and cable connections as well as handles and other accessories.

 

Easy to install

 

The adjustable shaft (for external handles) and mounting feet, along with snap-on auxiliary contacts and terminal shrouds create considerable savings in terms of installation time and costs. For example, the shaft can be adjusted to various installation depths, which eliminates the need for special cutting tools. This decrease handle installation times by up to 50%. In addition, switch disconnectors from 160…4000 A are extremely flexible regarding installation orientation. They work just as well installed horizontally or vertically, or even on the ceiling.
