The T279741S is a 1.5 kVA dry type distribution transformer manufactured by Acme Electric, designed for step-down voltage conversion in commercial and industrial applications. It features multiple primary voltage options (120, 208, 240, or 277 V) with a dual secondary output of 120/240 V, encapsulated construction with an electrostatic shield for enhanced electromagnetic protection, and copper windings for efficient power transfer. The transformer operates with a maximum temperature rise of 115°C and maintains UL insulation class 180°C rating, ensuring reliable long-term performance. Its wall-mounted design and quiet operation with sound levels below NEMA standards make it suitable for office buildings, retail facilities, and light industrial environments where low noise and compact installation are priorities.
