Link module for
circuit breaker and
contactor
Link modules are needed to make electrical and mechanical connections
between the circuit breaker and contactor to form a load feeder. Link mod-
ules are available for the following combinations:
You can find additional information about load feeders on busbar systems in
Chapter 5, "Fuseless load feeders".
Mounting circuit
breakers on busbars
The following illustrations show you how to mount circuit breakers in frame
sizes S00 and S0 onto busbar adapters (8US1..1-5D) and how to remove
them again, using frame size S00 as an example:
