Current transformers cable type
The ELA...
current transformers are intended for indoor use under the normal and severe conditions such as ships,
mines,
chemical industry etc.
They can be used in the mains at rated voltage up to 0.72 kV,
50 ÷ 60 Hz frequency and can operate in abbient temperature range from 248 K (-25°C) to 323 K (50°C).
The ELA current transformers are produced in accuracy class 0.2; 0.5; 1; 3 and have a raised rated voltage up to 1.2 kV and test voltage up to 6 kV,
which makes them possible for many applications
