Technical Drawing
![]()
- Corrosion resistance: 304 stainless steel construction withstands salt spray, chemical exposure, and high humidity.
- Environmental protection: NEMA 4X rating delivers dust-tight and water-tight performance, equivalent to IP66, for reliable operation in washdown and outdoor conditions.
- Durable construction: Continuous welded seams, EPDM gaskets, and all-stainless hardware maintain enclosure integrity under extreme stress.
- Safety and reliability: Dry-type design eliminates the risk of fluid leaks and fire hazards, making it ideal for enclosed marine spaces.
- Electrical isolation: Provides galvanic isolation between primary and secondary circuits, protecting sensitive equipment from voltage transients and ground faults.
- Low maintenance: No fluid monitoring or replacement required, reducing lifecycle costs.
- Vibration damping: Integrated shock mount brackets isolate the transformer from mechanical vibration and shock, common in marine and industrial settings.
- Enhanced durability: Reduces stress on windings and core, extending service life and improving operational stability.
- Easy installation: Pre-engineered mounting system simplifies integration into shipboard electrical rooms or industrial control panels
