installation completed
When inserted, depending the position the
disconnect lever, electrical connection (short
circuit) between the two terminal blocks can be
realised. lifting the TTB CM, the two (or more)
disconnect levers the terminal blocks are disengaged
from each other and can switched independently. Prior
to any re-energising the circuit, the needs be
pushed down into original position and the circuit closed. SCCB TTB short circuit bridge
