  • Non-Ventilated Resin-Encapsulated Transformers (H-Class Insulation)
    Non-Ventilated Resin-Encapsulated Transformers (H-Class Insulation)
    ET Series

    Non-Ventilated Resin-Encapsulated Transformers (with H-Class insulation) are characterized by a reduced noise level compared to ordinary dry-type or cast-resin transformers. Compact and installable in a number of different ways, these transformers are furthermore self-extinguishing. With a durable IP20 enclosure, these transformers come in Regular Type and "Silent" Type, for the lowest sound levels. Optional accessories include protective devices for overload and over-temperature protection. SPD for protection against lightning is also available.
