358C25 - ESAB 30kVA 575V to 460V 3-Phase Step-Down Transformer

Reliable Industrial Power Conversion with ESAB

The ESAB 358C25 Stepdown Transformer is a critical infrastructure component for industrial facilities operating on a 575V grid that require the operation of 460V machinery. In many Canadian industrial sectors, 575V (often referred to as 600V) is the standard line voltage, yet a significant portion of heavy-duty welding equipment and industrial machinery is manufactured to the 460V standard common in the United States and other markets. This mismatch can prevent the utilization of high-performance equipment. The ESAB 358C25 bridges this gap effectively, providing a robust 30 kVA power solution that steps down the primary voltage to a usable secondary level.

Engineered for durability and consistent performance, this 3-phase transformer is rated for 30 kVA, making it suitable for powering medium to heavy-duty welding power sources. It ensures that your sensitive welding inverters and transformers receive the correct voltage, protecting internal components from over-voltage damage while ensuring the arc remains stable and consistent. The unit is built to withstand the rigors of an industrial shop floor, featuring a rugged enclosure that protects the internal windings and core from physical impact and environmental contaminants common in metal fabrication environments.

Proper voltage management is essential for equipment longevity. Running 460V equipment on 575V power without a transformer is dangerous and will lead to immediate equipment failure. Conversely, using an under-powered transformer can lead to voltage sag under load, resulting in poor weld quality and potential damage to the transformer itself. The 30 kVA rating of the ESAB 358C25 offers ample headroom for many standard industrial welding setups, ensuring that current delivery remains smooth even during high-amperage starts. This unit is an indispensable asset for facility managers and maintenance operations looking to integrate diverse equipment into a unified power infrastructure.

Key Industrial Benefits:

• Seamless integration of 460V assets into 575V infrastructures.


• Protection of capital equipment from voltage incompatibility.


• High efficiency design minimizes energy loss during conversion.


• Robust build quality ensures long service life with minimal maintenance.
