Proper use
The Disconnect Control Unit is used as a main switch and for
selectively disconnecting individual sections of a materials
handling system. It combines the functions of main switch,
maintenance switch and cable protection device in one. It is ideal
for protecting several starters and long lines by allowing the
tripping currents to be set as required for the plant.
Any other usage constitutes improper use.
