ARCHIMEDE: the new intelligent thermoplastic distribution box
All V.B. thermoplastic distribution boxes are supplied with “ARCHIMEDE”: an acoustic-visual system which warns you if the earth is correctly working.
ARCHIMEDE checks and confirms you if the earth’s unloading is correctly working, so in this way you can work safely.
In the absence of the earth, ARCHIMEDE will get your attention through an acoustic signal and its led will change colour from green to red, warning you of the danger.
Because you can see and hear the difference!
