Three Phase Auto-Transformers IP-00 - Electrical Systems

Description

The three-phase autotransformers IP-00 are dry type and are tropicalized, their level of corrosion protection is very reinforced, as well as electrical insulation. The Auto transformer does not have galvanic isolation between the power supply and the use since it is the same winding, this makes it very attractive due to its low cost compared to the transformer.

There is the possibility of manufacturing custom products if the standard specifications are not required by the client.

Technical characteristics:

Concept	Values
Isolation	Class F
Frequency	50-60Hz
Type of protection	IP-00

REFERENCES:

There are different types of three-phase autotransformers, divided into two ranges of products: the ATT series of three-phase autotransformers and the ATTM series of three-phase maneuver autotransformers.

Applications:

IP-00 three-phase auto-transformers are used for:

Applications that require a neutral in a three-phase line that does not provide it.
Voltage changes from 400V to 230V and in the opposite direction, and other voltages on demand.

Observations:

Three-phase IP-00 autotransformers are manufactured according to IEC 96-2, IEC-742, EN-60742 and the indicated data can be modified as needed, without prior notice.
