It hasbeen designed for the disconnection of power lines according to CEI EN 60947-3, allowing the maintenance of downstream connected devices in safety, and for the control under load. The quick and safe opening mechanism guarantees very high performances both in current.

Thedisconnector, otherwise called voltage switch, has the same functions as a switch, but on a larger scale: it is, in fact, responsible for shutting off the flow of energy to the power distribution plants. This serves mainly to ensure the safety of the plant and primarily of the people who work inside since one of its peculiarities is to separate the flow of energy from the working environments. Another peculiarity of this instrument is the ability to detect defects in the electrical flow and isolate them. When the defect is corrected, the disconnector will ensure that the current flows normally again.
