Sontuoec 125A manual 1P,2P,3P,4P MCB types of changeover switch mcb size insulator switch manufactory
Application:
I-O-I Centre-Off changeover switches from 63A to 125A - 1P,3P, 2P and 4P - manual operated. Their compact design and modular format allows standard DIN rail mount and space saving in the electrical switchboard. Complies with BS EN 60947-3.
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-I )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 125A - 6kA - C curve to protect against short circuit and disconnection.
