Line of Three-Phase Isolation Transformers

The function of three-phase transformers is to raise or lower the voltage, according to the load requirements. The load is electrically isolated from the utility grid. It is suitable for powering more sensitive equipment that needs to be protected from the electrical grid.

Isolation Transformer Line - KTI

Ideal for industrial applications. They ensure effective electrical isolation between primary and secondary circuits, typically used in sensitive equipment.

PROTECTION LEVEL

It is a classification that indicates the level of protection provided by electrical equipment against the intrusion of foreign solid bodies (such as dust and objects) and the ingress of water.

IP23

They are suitable for use in indoor and sheltered environments. They offer protection against water droplets up to a maximum angle of 15°, and against solid objects with a diameter greater than 12.05 mm.
Button

IP54

They can be used in outdoor environments where they may be subject to adverse weather conditions, such as rain and dust.
Button

IP65

They can be used outdoors. They are fully protected against the entry of solid objects such as dust and water jets.
