About the Product

Intended for power systems of 7.2 kV or below, these single-phase coil molded potential transformers are compact and economical. Model EP-3SF2 features a laminated core and is fixed by two metal frames; cut-core models EP-3SF5 and EP-6SFK are fitted on a metal base. All of the models come with two fuses on the primary side and are insulated with Araldite® epoxy resin. The EP-3SF/6SF Series is characterized by high moisture resistance and excellent electrical properties. In addition, the EP-6SFK model can be used as an auxiliary power source for circuit breaker operation (see Specifications).
