Current Transformers

Fanox offers complete solutions providing, not only highest quality electronic protection relays, also required current transformers to get protection and measuring capability. Based on relays, different types of current transformers can be used, adapted to customer requirements, both mechanical and functional.

Regarding technical features, all required values that define a CT, as transformation ratio, burden, accuracy class, protection class, frequency, isolation level, ….are adapted to be completely compatible with Fanox electronic Relays.

Furthermore, in case customer has mechanical limitations or a specific CT Type is required, we can study customized production.
