Special accessories for fuseless load feeders

which are connected to the motor starter protector from above.
There are also special snap-on auxiliary switch blocks for the contactor, which are connected
from below.
These two accessories enable the fuseless load feeders to be wired simply, without the
cables having to be routed through the devices.
