Integrated protection and conditioning: The unit combines a protective MCCB with a ventilated transformer, delivering streamlined control schematics and faster fault isolation. Business impact includes reduced panel real estate and simplified maintenance, enabling faster commissioning on manufacturing lines and in retrofit projects. Application emphasis is on data centers and industrial panels where space, protection coordination, and reliability are critical.Energy efficiency and regulatory compliance: With DOE 2016 Efficient, 10 CFR Part 431 labeling, and UL Listed certification, the solution supports lower operating costs and compliance reporting. The 60 Hz, 45 kVA rating ensures scalable capacity for load growth in mid-size facilities, while minimizing energy waste across shifting demand. This aligns with sustainability objectives and procurement standards for engineering teams.Durable construction for harsh environments: Copper windings, 325 °C insulation, and a robust NEMA 2 enclosure paired with WS65 weather shielding deliver long service life in challenging floorspace conditions. This reduces maintenance intervals and extends mean time between failures (MTBF). Ideal for floor-mounted or wall-mounted installations, it simplifies install planning and service access across plant sites.Flexible wiring and mounting options: Tap sizes of 2 at +2.5% and 4 at -2.5% support voltage regulation for sensitive loads, while wiring connection 280BPB enables straightforward terminations. The 21.13 in depth, 24.88 in width, and 45.37 in height enable versatile mounting and quick integration into existing panel architectures. This translates to lower installation risk and faster project timelines.Reliability and safety in one package: Primary 480 V and secondary 208Y/120 V ratings, along with a 115 °C rise and UL certification, ensure dependable performance for three-phase applications such as panel retrofits and distribution boards. The integrated MCCB offers protective coordination with the primary side, reducing downstream faults and increasing operator safety.
