The Z44G11S25SS combines a robust hazardous location design with practical field adaptability, enabling safer power delivery in retrofit and new-build projects. Feature → Business Impact → Application: Encapsulated construction and EPZ design reduce ignition risk in Class I Division 2 zones, meaning safer start-up, fewer shutdowns, and streamlined compliance across oil and gas, chemical processing, and mining facilities. This translates to lower incident downtime and improved maintenance predictability for control rooms and remote equipment, where consistent voltage supply is critical. Feature → Business Impact → Application: Aluminum winding material lowers weight and material cost while maintaining durability, supporting easier crane or forklift handling during installation and service in limited-access areas. Use this transformer in plant power distribution networks that require reliable 25 kVA capacity with 440 V primary feeding 120/240 V secondary for control panels, lighting, and auxiliary systems. Feature → Business Impact → Application: -5% FCBN taps offer precise voltage optimization under load fluctuations, improving motor and control performance and reducing wasted energy in process lines. Feature → Business Impact → Application: NEMA 3R indoor-outdoor enclosure paired with a Grade 304 stainless steel enclosure option provides corrosion resistance and weather sealing, enabling outdoor installations near docks, yards, or exposed equipment while maintaining long service life. Feature → Business Impact → Application: UL Listed and Class I Division 2 rating provide regulatory compliance and third-party validation, reducing procurement risk and accelerating project approvals, particularly in regulated facilities. This product also supports straightforward integration with 2R wiring configurations and standard 182H frame size, aiding compatibility with existing footprints and mounting requirements.
