This time, our engineering department developed an low cost load break switch, which had for its object to control of a three-phase motor operating in hazardous areas.
In addition, the solution had to carry a signal of engine running to the operations center in a safe area.
How could it be otherwise, the system must have all security guarantees. The switch, in addition for guaranteeing accessibility, had to be candable in all positions.
