Wega 1.2 C vario is a 3-phase voltage detecting system. The built-in display test function at the front enables verification of the display of the installed and de-energized unit. To ensure flexibility, an adjustable capacitor cube is plugged in on the back of the device allowing the use of various balancing capacitors. For connection, either shielded or unshielded cables with flat connectors or system connectors can be used.
