Information About G280446G050
The G280446G050 is an indoor model in the nVent HOFFMAN SpectraCool G28 series and is designed for enclosure cooling in industrial environments. The unit operates at 460 VAC, 50/60 Hz, three-phase power, with a current rating of approximately 1.3/1.4 A and power consumption of 1,435 W. Current nVent documentation lists 4,900 BTU/hr (1,435 W), while earlier G28 performance documentation lists 4,600/4,900 BTU/hr depending on the rating basis. The air conditioner features a mechanical thermostat, filterless condenser operation, galvanized/steel construction, and an operating temperature range from -40°F to 131°F (-40°C to 55°C).
Key Features:
- 4,900 BTU/hr Cooling Capacity: Provides high-capacity heat removal for sealed electrical and industrial enclosures.
- 460 VAC Three-Phase Power: Designed for 460 VAC, 50/60 Hz three-phase electrical systems.
- SpectraCool G28 Series: Part of the G28 family of sealed enclosure air conditioners for industrial applications.
- Filterless Condenser Design: Uses a dust-resistant condenser coil that allows filterless operation in many indoor environments.
- NEMA Protection: Provides NEMA Type 3R, 4, and 12 enclosure protection when installed according to manufacturer requirements.
- Wide Operating Range: Designed to operate across temperatures from -40°F to 131°F (-40°C to 55°C).
- Steel Construction: Uses a light-gray steel housing for industrial enclosure installations.
- Mechanical Thermostat: Provides temperature control through a mechanical thermostat mounted on the enclosure side of the unit.
The G280446G050 delivers the reliability and precision required for maintaining controlled temperatures in electrical, automation, controls, drives, and power-distribution enclosures.
