Die Erklärung/Inhaltsangabe:For protection against atmospheric overvoltage of electric equipment insulation
alternate current by the frequency 50 - 60 Hz
Die ausführliche Beschreibung der Marke:For networks with any system of neutral grounding (15,
20, 35 kW) are being manufactured and for networks with effectively earthed neutral (33, 66, 110,
132, 150, 220 kW).
