Schneider Electric 11T145HDIT Power Transformer

Schneider Electric’s Square D 11T145HDIT is a dry-ventilated drive-isolation transformer rated at 11 kVA for three-phase motor-drive systems. The unit features a 460 V delta primary and a 460Y/265 V secondary designed for 60 Hz operation, with aluminum windings housed in a dry-type enclosure suitable for industrial environments. It weighs about 88.5 kg (roughly 195 lb), and its drive-isolation design supports harmonic mitigation for inverter-fed loads and SCR-based drives, helping to protect electrical equipment from harmonics and transient spikes. Schneider Electric literature describes the transformer as capable of delivering reactive current control for both AC and DC motor drives and emphasizes its role in isolating drives from the supply. The data also reference compliance characteristics such as alignment with harmonic standards (IEEE 519-1992) and overload considerations (IEEE-597 Class B), making it a purpose-built solution for industrial automation requiring reliable isolation and harmonic management.
