The technical characteristics of the meter type CDE – 01, made by NOVA INDUSTRIAL S.A. are as follows:/p>

  • high amplitude current pulse: 4/10 μs max. 100 kAv;
  • long-term current pulse 2000 μs: max. 800 Av;
  • starting current of the metering at lightning current pulse 8/20 μs: min. 250 Av;
  • switching starting current at switching current pulse 30/60 μs: min. 150 Av;
  • mass: approx. 1.1 Kg;
  • dimensions L x W x H: 175 x 80 x 60 mm.

The CDE – 01 type meters can be mounted suspended by their own terminals (in case the earthing is done with flat strips) or on a support, with the help of fastening parts available on request.
