Hazardous-area rating and resin-encapsulated construction reduce risk in Class I, Division 2 environments. The encapsulation protects copper windings from moisture and contaminants, lowering insulation degradation and maintenance cycles. This rugged design is well-suited for chemical plants, refineries, and other classified locations where continuous power and reliability are non-negotiable. Copper windings with resin encapsulation provide superior thermal performance and durable insulation. That translates to longer service intervals, lower fault rates, and improved uptime for 75 kVA loads. In practice, this enables control cabinets and motor drives to operate within temperature limits without frequent recalibration. Three-phase operation with 600 Vac primary and 208Y/120 Vac secondary supports efficient, safe power delivery for automation panels. The 60 Hz design minimizes voltage droop across feeders and simplifies integration with existing electrical systems. This combination reduces wiring complexity and improves control reliability in demanding production lines. NEMA 3R enclosure and hazard-area certifications simplify field approvals and outdoor/indoor installation. NEC/CEC compliance and UL certification coverage bolster regulatory readiness in cross-border facilities. Having these credentials streamlines procurement and reduces the need for extensive on-site testing. Physical footprint and weight require planning: dimensions are 30.28 in length, 32.06 in height, 15.67 in width, and 1460 lb. Plan for crane access, foundation, and service clearances to ensure safe handling and maintenance. Compact footprint supports retrofit projects where space is at a premium. Documentation and design support: SP3D package, brochures, catalogs, installation instructions, and UL certification reports. These assets cut engineering time, support accurate BOMs, and speed commissioning. Leverage these documents to validate spec fit and expedite approvals for hazardous locations projects.

FAQs
The XDT3D75 is a three-phase, 75 kVA dry-type transformer with a 600 Vac primary and 208Y/120 Vac secondary, designed to align with standard industrial power architectures. It supports common panel distributions and control circuits, but its heavy weight (1460 lb) and footprint (30.28 in L x 32.06 in H x 15.67 in W) require proper mounting, crane access, and suitable foundations.
Installers should verify area classification is Hazardous/Classified Locations and ensure NEC/CEC compliance. The XDT3D75 comes with a NEMA 3R enclosure and UL certification references for hazardous environments, plus installation sheets such as the IF XDT instruction sheet to guide wiring methods, clearance, and mounting. Plan for proper grounding and lockout/tagout during commissioning.
Plan for a footprint of approximately 30.28 in deep, 32.06 in tall, and 15.67 in wide, with a total weight around 1460 lb. Ensure crane access for movement, a stable foundation, and sufficient service clearances for connections, ventilation, and future maintenance activities.
Resin-encapsulation seals windings from moisture and contaminants, improving insulation resilience and reducing maintenance cycles. Copper windings provide superior electrical conductivity and thermal performance, supporting reliable operation under continuous duty at 75 kVA. This combination translates to lower fault rates and longer service life in demanding industrial environments.
