Overview

Hammond Power’s Y045QTCH3L0U 45 kVA three-phase autotransformer delivers precise voltage adjustment for industrial power distribution systems. Designed for step-up or step-down applications, this autotransformer corrects supply voltage to match load requirements without isolating circuits, offering a cost-effective alternative to isolation transformers. Rated for 600Y/480Y to 400Y/240Y/208Y voltages at 60 Hz, it supports 45 kVA continuous duty with a 130°C insulation system (80°C rise) and optional 180°C (115°C rise) encapsulated units for harsh environments. UL Listed (File: E258346, UL1604, Class I, Division 2), CSA Certified (File: LR3902), and ABS Type Approved (Certificate No.: 04-HS435190/1-PDA), the Y045QTCH3L0U meets rigorous safety and performance standards. Heavy-duty Type 3R enclosure with optional Type 4/4X stainless steel enclosures ensures durability in indoor/outdoor applications. Top-accessible high/low voltage leads or copper tabs simplify wiring, while standard side/rear conduit knock-outs (excluding stainless enclosures) accommodate flexible installation. With impedance under 3%, NEMA ST-20 compliant sound levels, and optional low-noise configurations, this autotransformer integrates seamlessly into distribution panels, motor control centers, and industrial machinery. Ideal for facilities requiring voltage correction for 208Y/120V, 240Y/120V, or 480Y/277V systems, it eliminates the need for costly isolation transformers when circuit isolation isn’t required.
