CMT11-1

● Application

JIELI ELECTRICAL 2 Way / Centre-Off changeover switches from 25A to 63A – 1P, 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.

● Products Packing show

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 powergrid 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 locationof manual changeover device with centre “off” position in the main switch board.

The incoming changeover must be protected with an appropriateMCB 63A - 6kA - C curve to protect against short circuit anddisconnection.

NOTE 1: In Australia and NZ, the Main Supply Neutral upstream of the MEN connection is NOT allowed to be switched. (AS/NZS 3010: Electrical installations - Generating sets).

NOTE 2: Refer to AS/NZS 3000, 3010 and local Service and Installation Rules for specific requirements.
