Special accessories for fuseless load feeders
Accessories are also available which have been optimized for fuseless load feeders. These
include the transverse auxiliary switches with 1 CO contact or 1 NO contact + 1 NC contact,
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.
