• Primary Voltage: 480V Delta

Non-ventilated enclosures are used in environments where large quantities of dust, airborne contaminants, metal particles, or moisture make ventilated transformers impractical. These transformers are also used when water spray from any direction is possible. The 150° C rise transformers are built using 220 class insulated core and coil assemblies similar to ventilated units Core and conductors are oversized to maintain proper temperature rise with limited cooling capacity of a non-ventilated enclosure Larger and heavier than the same kVA and voltage ventilated equivalent Non-ventilated enclosures meet protection code IP55 (dust and jetting water protection) per IEC-605.29 While not listed to a specific NEMA standard, they are suitable for indoor or outdoor use
