A main switch, also known as a main switch isolator or main switch disconnector, is a manually operated device used to isolate an electrical circuit from its power source for maintenance or emergency purposes. It is typically located in a consumer unit or distribution board and serves as the primary means of cutting off power to the entire installation or specific circuits.
Timelec offers a variety of main switch products designed to ensure safety and reliability in electrical systems. Understanding these products requires an overview of their functionality and the specific items in the Timelec lineup.
