Selling Policy 25-000 - Distribution and Control Products and Services
Encapsulated hazardous-location design provides isolation from ambient contaminants, reducing corrosion and arc-flash risk, thereby enhancing operator safety and equipment reliability. Business impact: safer operation and longer service life for critical assets in explosive atmospheres; application: chemical plants, oil and gas facilities, and other environments requiring Class I Division 2 compliance. Three-phase 45 kVA transformer with 460 V primary and 208Y/120 V secondary delivers scalable power distribution to control panels, motor starters, and automation loads, reducing wiring complexity and optimizing panel design. Copper windings improve thermal performance and efficiency, lowering energy losses and enabling sustained operation under peak loads. Voltage regulation features, including a -5% FCBN tap, help maintain stable output during supply fluctuations, minimizing equipment stress and extending component life. Weathershield indoor-outdoor enclosure, 244H frame, and 66I wiring connection support robust installation in both indoor plant rooms and outdoor locations, simplifying site planning and retrofit projects. Warranty and service options provide post-sale support and risk mitigation for long-term operations, while certifications remain regionally specific—verify current approvals with the manufacturer to ensure compliance in your jurisdiction.
