Bus-section panel (connecting panel)

The bus-section panel is used to separate or connect

parts of the installation (bus-sections).

The bus-section panel in the illustration consists of two

panels; one panel contains the circuit breaker, the other

panel is the bus riser panel. The Power Xpert

UX has

designs that allow for the bus-section to be mounted

either on the Left or the Right of the riser panel. An

additional option with Power Xpert

UX Switchgear is

that the bus riser panel can be supplied suitably

equipped with a number of units:

- Circuit Breaker

- Contactor

- Earthing Truck

- Voltage Transformer

- Disconnect/Isolation
