Switch Disconnector 1P - Automatic Tripping. View Electrical symbols.pptx from MATHEMATICS CALCULUS at Lyceum College (Pty). They work just as well installed horizontally or vertically, or even on the ceiling. Electrical IEC 60617 / BS 3939 symbols representing isolators, disconnectors.

In addition, switch disconnectors from 160…4000 A are extremely flexible regarding installation orientation. This decrease handle installation times by up to 50%. For example, the shaft can be adjusted to various installation depths, which eliminates the need for special cutting tools. 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. The symbol above represent an isolator switch. The devices can be optimized in relation to busbar and cable connections as well as handles and other accessories. It is a also known as disconnector switch or isolator switch is used for isolating and completely de-energizing the circuit. The modular design enables 2-, 3- and 4-pole installation with different position of the switching mechanism to suit your needs and spacial requirements. Durability has been ensured by testing switches against the IEC60947- 3, UL508, UL98 and CSA standards.Īll our switches have been designed for easy and cost-efficient installation, maintenance and use. They are designed to be virtually maintenance-free across their entire extended lifespan and offer reliable performance in any and all possible circumstances. ABB switch-disconnectors are designed, built and tested for the best possible performance.
