Transformer 3-phase 3LTE20.0 3LT100M25 3LT400 3LT500 230V to 400V NORATEL Việt Nam

Noratel 3-phase transformers are high-quality industrial transformers designed to convert three-phase voltage from 230 V to 400 V or vice versa, while providing excellent electrical isolation between primary and secondary circuits. These transformers are widely used in industrial power systems, buildings, manufacturing plants, automation systems, and electrical cabinets to ensure stable power supply and equipment protection.

Thanks to their galvanic isolation design, Noratel transformers help eliminate earth faults, reduce electrical noise, and improve system safety, making them ideal for sensitive equipment and critical industrial environments.

Typical Applications

Noratel 3-phase transformers are used in many fields, including:

• ⚡ Three-phase voltage conversion systems for machines requiring 400 V power from 230 V networks.

• 🏭 Industrial machinery and motor systems such as pumps, compressors, conveyors, CNC machines.

• 🔌 Control panels and automation systems (MCC, PLC cabinets) for safe and stable power distribution.

• ❄️ HVAC, refrigeration, and water treatment systems, where reliable voltage and isolation are essential.

• 🏗️ Infrastructure and commercial buildings, providing safe power transformation for large loads.

These transformers ensure consistent performance, minimize downtime, and protect expensive electrical equipment.
