Short Description

Units are enclosed in a NEMA 2 drip proof metal enclosure with natural-draft ventilation. Core-and-coil assembly is mounted on rubber isolation pads to reduce noise. Weather shield kits are available for conversion to a NEMA 3R enclosure suitable for outdoor service. NEMA 3R stainless steel (Type 316) enclosure is available up to 150kVA. To specify a stainless steel enclosure, substitute an “S” in the fifth character in the GE product number. Example: 9T83B3874 changes to 9T83S3874. All QL model product numbers begin with 9T6, 9T7, 9T8, or 9T9.
