Main Components

1 switchgear: switch-disconnector and earthing switch in an enclosure filled with SF6 and satisfying "sealed pressure system" requirements.
2 busbars: all in the same horizontal plane, thus enabling later switchboard extensions and connection to existing equipment.
3 connection: accessible through front, connection to the lower switch-disconnector and earthing switch terminals (IM cubicles) or the lower fuse-holders (PM and QM cubicles). This compartment is also equipped with an earthing switch downstream from the MV fuses for the protection units.
4 operating mechanism: contains the elements used to operate the switchdisconnector and earthing switch and actuate the corresponding indications
(positive break).
5 low voltage: installation of a terminal block (if motor option installed), LV fuses and compact relay devices.
