Schneider Electric 150T76HIS Three Phase Transformer

Square D by Schneider Electric 150T76HIS is a 150 kVA three‑phase distribution transformer with a 480 V primary and a 480Y/277 V secondary, built for commercial and light‑industrial power distribution. It delivers a three‑phase, wye‑connected (neutral) 480Y/277 V secondary, enabling 277 V lighting and other loads while feeding 480 V three‑phase equipment on the primary side. The 150T76HIS configuration is documented by Schneider Electric/Square D and is listed by distributors and retailers as a 150 kVA transformer with PRI.480 and SEC.480Y/277, 3‑phase. Commonly described as a pad‑mounted low‑voltage distribution transformer, it balances a substantial load rating with a relatively compact footprint suitable for outdoor or indoor installations in commercial facilities. This exact model is referenced by multiple distributors (including Cooper Electric) under catalog number 150T76HIS, reinforcing its voltage configuration and three‑phase design.
