Load break switch
A load break switch is a disconnect switch that has been designed to provide making or breaking of specified currents.
This is accomplished by addition of equipment that increases the operating speed of the disconnect switch blade and the addition of some type of equipment to alter the arcing phenomena and allow the safe interruption of the arc resulting when switching load currents.
