Circuit breaker panels are used as incoming or outgoing feeder panels. The 3AH vacuum
circuit breaker is mounted on a truck for pushing the vacuum circuit breaker into the panel.
The vacuum circuit breaker can break the normal and short-circuit currents specified on the
rating plate.
Bus sectionalizing consists of a circuit breaker panel and a bus riser panel.
Metering panels are used for measuring the voltage at the busbar system. The metering
panel is equipped with a metering truck.
Disconnecting panels can be used for no-load disconnection of two busbar sections in bus
sectionalizing.
Busbar connection panels are bus riser panels with a panel connection for cables.
