IP65 Three Phase Transformers

The IP65 Three Phase Transformers are used in installations where we need a voltage change but without any requirement regarding insulation or safety.

For three-phase IP-65 transformers, installation is recommended where a high degree of protection is required since it will be completely free of dust as well as water in any direction.

The IP-65 Three-Phase Transformers are used for environments with very demanding external conditions since the metal casing protects the transformer from corrosive materials, water, humidity. They are also used in environments with a high risk of explosion such as chemical industries.

The Three-Phase Transformers IP-65 are manufactured according to IEC 96-2, IEC-742, EN-60742 and the indicated data can be modified as needed, without prior notice.
