WS68
Feature: Integrated breaker and ventilated transformer combines protection and power conversion in one assembly. This reduces BOM, minimizes panel footprint, and lowers installation labor, delivering faster project execution in new builds or retrofits. Application: Industrial control panels and machine enclosures. Feature: 225 kVA rating with 3-phase 480 V primary and 208Y/120 V secondary. This provides reliable control power for multiple circuits, reduces voltage drop, and supports scalable control architectures in heavy equipment and process lines. Feature: Copper windings and 242 °C insulation with a NEMA 2 enclosure. This improves thermal performance and durability for indoor environments, reducing maintenance costs and downtime. Feature: Secondary MCCB NGS308033EC and tap changer options (2 at +2.5%, 4 at -2.5%). This enables enhanced protection and flat-topping voltage regulation to safely start and run sensitive loads. Feature: DOE 2016 Efficient and UL Listed compliance. This meets regulatory requirements while delivering energy savings, supporting plant-wide energy management goals and regulatory auditing. Feature: Weathershield WS68 option supports outdoor or harsh environments where indoor protection is not feasible, extending installation flexibility.
