G280446G060

Overview

The nVent HOFFMAN G280446G060 is a SpectraCool MCLG series indoor/outdoor enclosure air conditioner designed for narrow enclosures. It provides a cooling capacity of 4900 BTU/hr at 50/60 Hz. The unit operates on 400/460 V AC, drawing 1.7 A at 400 V and 1.9 A at 460 V. Constructed from galvanized sheet metal with a light gray finish, it measures 28.55 in H x 16.97 in W x 10.1 in D. It features a basic mechanical thermostat and terminal connections, suitable for NEMA 3R/4/4X/12/IP34/56 environments.

Feature Summary

• Designed specifically for narrow floor- and wall-mount enclosures with 12-inch depth constraints.
• Constructed from galvanized sheet metal for durability in indoor and outdoor settings.
• Equipped with Remote Access Control (RAC) capabilities for operational monitoring.

Applications

• Climate control for 12-inch deep industrial floor-mount enclosures
• Temperature regulation for wall-mount electrical cabinets
• Protection of sensitive electronics in NEMA 4/4X rated environments

Procurement Notes

Verify that the target enclosure depth does not exceed 12 inches (300 mm), as this unit is engineered for narrow profiles. Confirm the required voltage matches either 400 V or 460 V AC to ensure correct current draw specifications. Ensure the installation environment meets the specified NEMA 3R/4/4X/12/IP34/56 ratings for appropriate ingress protection.

Selection Notes

Select this model when space is limited to 12-inch deep enclosures but higher cooling capacity than standard units is required. Choose based on the specific supply voltage available (400 V vs 460 V) to determine the correct amperage rating. Consider the RAC feature if remote monitoring of the cooling system status is necessary for facility management.

Part Context

This unit belongs to the Hoffman SpectraCool MCLG series, which specializes in compact cooling solutions. The G28 prefix indicates the 4000-5000 BTU/hr capacity range within the product line. It serves as a sealed cooling solution for harsh environments where traditional ventilation is insufficient.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing mounting brackets and electrical connections before considering alternative models from the same manufacturer series.
