G280446G050

Overview

The G280446G050 is a Spectracool MCLG series indoor enclosure air conditioner manufactured by nVent HOFFMAN. It provides 4,900 Btu/hr cooling and heating capacity with washdown capability. The unit operates on 460V AC at 1.3/1.4 A current draw, supporting 50/60 Hz frequencies. Designed for NEMA 3R/4/12 enclosures, it features wall-mount installation. Physical dimensions are 28.55 inches in height, 16.97 inches in width, and 10.1 inches in depth.

Feature Summary

• Provides simultaneous cooling and heating functionality for controlled environments
• Constructed with washdown-resistant design suitable for demanding industrial conditions
• Engineered specifically for integration into NEMA 3R, 4, and 12 rated enclosures

Applications

• Climate control for industrial electrical enclosures requiring washdown protection
• Temperature regulation for equipment housed in NEMA 4 or 12 rated cabinets
• Indoor applications requiring 460V three-phase power supply management

Procurement Notes

Verify that the target enclosure meets NEMA 3R, 4, or 12 ratings to ensure compatibility with this unit's design specifications. Confirm the availability of a 460V AC power source with 50/60 Hz frequency support before procurement. Ensure sufficient internal space within the enclosure accommodates the specified physical dimensions of 28.55 x 16.97 x 10.1 inches for proper wall-mount installation and airflow.

Selection Notes

Select this model when both cooling and heating capabilities are required within a single unit for indoor industrial environments. It is appropriate for systems utilizing 460V three-phase power where washdown resistance is necessary. Consider this option for NEMA 3R, 4, or 12 enclosures needing precise thermal management without separate heating devices.
