Panel design
6 Panel design
6.1 Basic design
In the basic design, NXAIR is available both as withdrawable and as truck-type switchgear. In the basic
design as withdrawable switchgear, the removable part is taken out of the panel or inserted in the panel by
means of a service truck.
In the basic design as truck-type switchgear, the removable part is always positively combined with a service
truck. For truck-type switchgear, this means that always the complete truck is taken out of the panel or
inserted in the panel.
The basic operation or interlocking of the switching devices in the two basic designs, such as:
• Switching the circuit-breaker to CLOSED position or OPEN position
• Racking the withdrawable part / switching-device truck to service position or test position
• Switching the feeder earthing switch to CLOSED position or OPEN position
• Mechanical or electrical interlocking of the individual devices in the panel
is identical.
