Low voltage outdoor current transformers ELA N
ELA N current transformers are designed to supply circuits of power equipment measuring systems with maximal voltage of 0.72kV, for the cable, the bus-bar or bushing on the low voltage side of the transformer.
The current transformers can operate in the ambient temperature range from -35°C to + 40°C in indoor and outdoor conditions.
The secondary side terminals are led as a cable with specified cross section and length. The rated load is determined on the end of the cable.
The ELA N current transformers with 0,2; 0,5; 0,2S and 0,5S accuracy classes may be calibrated in the Central Office of Measures.Ask for product
