Made with an accurately machined steel
sheet enclosure and painted with high resistance epoxy powder. Execution
to be installed on the floor.
This board is usually combined with the automatic switchboard of a
generator, to get a remote changeover from mains to generator and
vice-versa.
The control logic of the remote changeover is located in the generator
automatic switch board.
POWER SECTION
-
For powers up to 125 A, the power switching
is got through a pair of remote control switches equipped with
electrical and mechanical interlock, to prevent a parallel presence of
generator power and mains power as well.
-
For powers higher than 125 A, the power
switching is got through a motorized 4-poles switch, equipped with
electrical and mechanical interlock, to prevent a parallel presence of
generator power and mains power as well..
