Circuit Breaker Operation Power Source (Select Models)

About the Product

Each EP-1S Series single-phase potential transformer features a resin-insulated coil and is fixed on supporting metal pieces on the front and back sides. Select models of the EP-1S Series can be used as an auxiliary power source for circuit breaker operation. All models, with their excellent moisture resistance and high insulation, are well-suited for humid locations. These indoor low-voltage potential transformers are furthermore characterized by great safety and a high-quality exterior.
