FAQs
Plan for a compliant mounting location with proper ventilation and drainage. Use the 243H frame for compatibility with standard racks or enclosures, connect via 68B wiring, and ensure the enclosure remains sealed to preserve its IP-style protection in hazardous areas. Verify UL Listed labeling and maintain clearances per Eaton installation guidelines.
The transformer is a three-phase unit rated at 30 kVA. It provides a 480 V primary input and a 208Y/120 V secondary output, suitable for feeding logic controllers, MCCs, and downstream equipment while maintaining tight voltage regulation across loading conditions. It operates at 50/60 Hz to accommodate global industrial systems.
Yes. It is designed for Class 1 Division 2 environments (Groups C and D) with a protective encapsulated design and NEMA 3R enclosure, offering robust protection against moisture, dust, and corrosive exposure. This combination supports safe operation in refinery and chemical processing applications where ignition risks must be mitigated.
It carries UL Listed certification and uses a Grade 304 stainless steel enclosure with a NEMA 3R rating, suitable for indoor-outdoor use. The EPTZ design, 115 °C rise, and copper windings add reliability, while the Class 1 Division 2 rating ensures compliance in hazardous environments across 50/60 Hz service.
