FAQs
The transformer is designed for hazardous locations with Class I, Division 2 compliance (Groups A–D) and a rugged NEMA 4X, 316SS enclosure suitable for indoor-outdoor use. It supports 60 Hz, three-phase service with a 480 V primary and 208Y/120 V secondary, making it compatible with control panels, switchgear, and outdoor electrical housings in demanding industrial settings.
With a 30 kVA rating, a 480 V delta primary, and a 208Y/120 V secondary, the unit efficiently steps down mains to usable control and auxiliary voltages. This reduces transformer count, minimizes voltage drop, and enhances motor start-up performance in distributed plant networks, while preserving power quality in harsh environments.
Yes. The Z48G28T30S64X is UL Listed and designed for hazardous locations with Class I, Division 2 compliance. It uses a NEMA 4X enclosure and a 316 stainless steel (316SS) enclosure surface, providing reliable protection against dust, water ingress, and corrosive atmospheres in demanding facilities.
The transformer employs aluminum windings and a 180 °C insulation class, offering good thermal stability under load. Routine checks should include insulation integrity, enclosure seals, and cooling pathways. Its encapsulated design reduces dust ingress, while the rugged enclosure minimizes corrosion risk, extending service intervals in harsh environments.
The unit delivers improved safety and reliability in hazardous locations, lowering unplanned downtime and compliance-related delays. Although upfront costs are higher than standard transformers, the UL Listing, Class I, Division 2 certification, and NEMA 4X enclosure translate to faster permitting, reduced maintenance, and longer intervals between replacements in demanding facilities.
