To complement our wide range of manual change-over switches, we also offer open transition manual change-over switches designed according to CE certification standards in a power range from 160 to 800 Amperes.
Our switches come with a real one pole construction in even higher ratings (one line per power line), creating savings in terms of energy consumption by reducing power loss. A single terminal per pole across the entire range also eliminates the need to use additional fixing sets to do connections.
Change-over switches by GRL are extremely well suited for heavy duty applications. They are equipped with CTI (comparative tracking index) of over 600 V, making them great for use in tropical environments.
A changeover switch switches a house’s electricity supply from the general grid power supply to a “generator system” in case of power outage. The changeover switch connects to the main power grid, generator or alternate source and the house wiring. When you switch or “Change over” all the power on that circuit changes from either Grid or Generator. (not allowing it to flow back into each other (Grid and generator))
