About the Product
Potential transformers EPF-3SF1 and EPF-6SF2 are primarily mounted on switchgear (3.3kV and 6.6kV, respectively) as an auxiliary power source for circuit breaker operation. Compact and of a flatter shape than other models, these potential transformers are mounted on top of the power switch as an operation power source and are compatible with short-interval large output. With Araldite® epoxy resin as insulation, these potential transformers also feature a Class-F heat-resistant insulation material for the coils. Two fuses on the primary side offer protection against overload and short circuit currents. EPF-3SF1 and EPF-6SF2 potential transformers are characterized by a high-quality exterior, excellent moisture resistance, and superior electrical performance.
