CMT11-1 manual changeover switches are a unique solution for secure supply of power to your facility. They are available for single (25A, 40A or 63A) and three phase (40A or 63A) applications including the switching of generators.
The changeover switches connect the critical loads/ circuits, the main power grid, the generator or an alternate source.When manually operated, the power flowing to the critical loads/circuit changes from either the main power grid or generator, preventing back feed into each other
Wiring Diagrams for the use of changeover switches (I-0-II) with stand-by generators Stand-by generator or Alternative supply generator: typical location of manual changeover device with
centre "off" position in the main switch board.
The incoming changeover must be protected with an appropriate MCB 63A - 6kA - C curve to protect against short circuit and disconnection.
