SG3A0225KB

Description

The HPS SG3A0225KB transformer is a high-performance general-purpose distribution transformer designed for use in electrical distribution systems rated for 600 volts and below. This transformer is ideal for supplying various loads, including appliances, lighting, heating, and motorized machinery. Available in both ventilated and totally enclosed configurations, the SG3A0225KB ensures reliable operation in diverse environments. It’s essential to note that for non-linear loads, this transformer may need to be derated to accommodate the additional heat generated from harmonic losses, as outlined in the DOE 10 CFR Part 431/TP1 standards.

With a power capacity of 225 kVA, the SG3A0225KB features a primary voltage of 480 Delta VAC and a secondary voltage of 208Y/120 VAC. It operates at a frequency of 60 Hz and boasts an impressive efficiency rating of 98.94%. The transformer comes equipped with lug/pad connections for straightforward installation and is housed in a NEMA 3R indoor/outdoor enclosure, making it a versatile choice for various applications.
