Integrated breaker and ventilated transformer assembly reduces footprint and simplifies wiring, enabling tighter panel layouts. This translates to faster commissioning, lower labor cost, and easier serviceability in busy plant environments. Applications include control panels and motor control centers where space is at a premium and cooling is critical. Copper windings with 230 °C insulation deliver robust thermal performance and long-term reliability, achieving an 80 °C rise under typical load to help meet temperature targets while maintaining efficiency. Enclosure is NEMA 2, suitable for indoor use, with floor mounting support and a robust 943SD frame for stable installations in switchgear rooms. Tap settings of 2 at +2.5% and 4 at -2.5% provide practical voltage adjustment for site variation while wiring is streamlined by 280BSB connections. DOE 2016 Efficient and UL Listed certification offer regulatory confidence and energy savings across the lifecycle. Weathershield WS67 option enhances outdoor or harsh environments, expanding compatibility with plant layouts. Weight and dimensions (1443 lb, 31.5 in L, 34.5 in W, 59.52 in H) support standard rigging and floor installation, delivering a lower total cost of ownership through reduced maintenance, fewer components, and improved reliability in industrial power distribution.

FAQs
Mounting requires a floor-supported frame (943SD) with indoor, clean environment suitability (NEMA 2). Ensure adequate clearance for convection cooling, proper access to the 280BSB wiring connection, and alignment with adjacent components to minimize heat buildup. Coordinate with hoisting equipment for the 1443 lb unit and verify vibration isolation as needed in high-cycle environments.
The unit is rated for 112.50 kVA, three-phase, with a 480 V primary and 208Y/120 V secondary, operating at 60 Hz. It uses copper windings and supports an 80 °C rise, with copper windings and 230 °C insulation. Tap settings include 2 at +2.5% and 4 at -2.5%, and it is designed for rugged duty in industrial power distribution.
Ideal for control panels, motor control centers, and other industrial power distribution points requiring integrated protective and conversion features. It suits plant-wide power distribution in manufacturing and processing environments, where space, cooling, and regulatory compliance drive a compact, efficient solution with UL listing and DOE efficiency.
This transformer is UL Listed and compliant with DOE 2016 Efficient standards, reflecting compliance with DOE 2016 Efficient labeling and 10 CFR Part 431 requirements. The NEMA 2 enclosure provides indoor protection, while the 80 °C rise rating supports predictable thermal performance in regulated facilities.
The integrated breaker-transformer design reduces component count, wiring complexity, and installation time, lowering upfront labor costs. Copper windings improve thermal efficiency and reliability, contributing to lower energy waste and longer service life. The compact footprint also simplifies spare parts planning and reduces total cost of ownership across the asset lifecycle.
