Selling Policy 25-000 - Distribution and Control Products and Services
Encapsulated hazardous-location design with EPTZ construction reduces ignition risk and simplifies installation in Class I Division 2 environments. Business impact: enhanced safety compliance, lower incident potential, and reduced field modifications; Application: chemical plants, oil & gas facilities, mining sites. Copper windings deliver high conductivity and thermal performance, improving efficiency and reducing heat-related losses. Application: critical process lines and motor drives where consistent voltage quality matters. The 45 kVA rating supports scalable distribution from 480 V to 380Y/220 V, enabling common plant substations to serve multiple loads without oversized equipment. Business impact: lower capital cost and optimized space. Application: panel boards and control centers in hazardous zones. Two taps at -5% FCBN provide simple voltage adjustments to maintain regulator performance under load swings; Business impact: improved voltage stability and reduced equipment wear in variable-demand environments. Application: feeding evolving production lines with tighter voltage tolerance. NEMA 3R enclosure with indoor-outdoor capability and Weathershield supports reliable operation in damp or outdoor settings; Business impact: extended service life, fewer separate enclosures, and easier maintenance; Application: outdoor electrical rooms and exposed installations. The transformer’s 3-phase, 60 Hz design aligns with standard plant electrical systems; Business impact: straightforward integration and predictable performance across equipment fleets; Application: heavy industrial automation and distribution networks. UL Listed certification and hazardous-location design address regulatory and insurer expectations, while the rugged frame (244H) and 950 lb mass convey robustness for demanding environments; Business impact: reduced downtime and long service intervals. Application: retrofits and new-builds in hazardous zones requiring durable power conversion.
