Class I Division 2 hazard-rating ensures safe operation of power distribution in environments with flammable atmospheres. The Z48N11S05X delivers 5 kVA of power at a 480 V primary and 120/240 V secondary, supporting control panels and instrumentation without overloading critical circuits. In oil refineries, chemical plants, and mining facilities, this combination translates to reduced risk, regulatory compliance, and predictable performance from the moment of installation. EPZ encapsulation paired with aluminum windings protects insulation from moisture and dust ingress while maintaining efficient heat transfer. This rugged construction minimizes field maintenance in challenging environments and helps pass NFPA 70E risk assessments, keeping downtime to a minimum. The compact form factor also simplifies integration with existing Eaton-based control systems and panel boards. Fixed 480 V primary to 120/240 V secondary with no taps reduces wiring errors and installation time. The 5 kVA rating covers common load groups for industrial controls, instrumentation, and small motors, while 50–60 Hz compatibility supports global operations. A single-phase design simplifies installation in space-constrained electrical rooms. NEMA 3R enclosure and Weathershield design enable reliable indoor-outdoor service, so outdoor installations or partially sheltered locations are feasible without extra housings. The rugged enclosure works with typical conduit fittings and 524H wiring connections, ensuring clean, repeatable field terminations and dependable electrical connections under harsh conditions. UL Listing and CSA Certification, plus a one-year (or 18-month from shipment) warranty, provide clear risk transfer for procurement teams. The transformer’s small footprint, established Eaton service support, and readily available catalogs and datasheets help streamline procurement cycles and maintenance planning in regulated industries.

FAQs
Z48N11S05X is intended for Class I Division 2 locations, which means the enclosure and insulation must withstand flammable atmospheres. Install on a clean, level surface with accessible terminations, maintain proper clearance for conduits, and use the 524H wiring method for safe connection to control circuits. The unit’s UL Listed and CSA Certified status confirms compliance with applicable electrical codes.
EPZ encapsulation places windings in a sealed, epoxy-impregnated matrix that resists moisture, dust ingress, and chemical exposure common in hazardous plants. This design reduces insulation degradation and field faults, improving MTBF. For maintenance teams, fewer interventions translate into lower lifecycle costs and less downtime during plant shutdowns.
The transformer provides a 480 V primary and a 120/240 V secondary, rated at 5 kVA. It operates at 50–60 Hz and is single-phase, making it suitable for feeder circuits, control panels, and instrumentation in compact electrical spaces. With no taps, voltage remains fixed for predictable performance across installations.
Yes. The Z48N11S05X uses a NEMA 3R enclosure with Weathershield for indoor-outdoor service, enabling reliable outdoor or partly sheltered installations without extra housings. Ensure proper conduit routing and mounting per Eaton guidelines, and verify compatibility with nearby equipment in outdoor industrial settings.
The unit carries UL Listed and CSA Certified marks, aligning with hazardous-location safety standards. Warranty terms follow Eaton policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This provides procurement confidence and supports long-term asset management in regulated industries.
