SG3A0150KB

Description

The Hammond Power Solutions SG3A0150KB is a high-quality, dry-type general-purpose distribution transformer rated for voltages of 480 volts and below. This versatile transformer is designed to supply power to various loads, including appliances, lighting, heating systems, and motorized equipment from electrical distribution systems.

This model features a robust bolt-together enclosure, offering an economical alternative to fully welded steel enclosures in applications where the latter isn't required. The NEMA 3R rating ensures suitability for outdoor use, protecting against rain and snow. For non-linear loads, it is essential to note that all standard DOE 10 CFR Part 431/TP1 dry-type 150kva transformer amps distribution, including the HPS SG3A0150KB, should be de-rated to account for extra heat generated by harmonic losses.

Key Features of HPS SG3A0150KB 150 KVA Transformer:

• Aluminium winding.
• Meets latest U.S. DOE 10 CFR part 431 efficiency standards.
