G280446G802

Overview

The G280446G802 is a SpectraCool AC rack-mounted thermal management unit manufactured by Hoffman Enclosures, Inc. It provides 4000 BTU/hr cooling capacity and operates on 460 VAC power. The unit features a mechanical thermostat for temperature control and utilizes terminal block connections. Designed for both indoor and outdoor environments, it offers NEMA Type 4X and Type 3R protection ratings. The device has an operating temperature range of -40 to 125 °F (-40 to 52 °C) and draws a maximum current of 2.5 A.

Feature Summary

• Provides active cooling with 4000 BTU/hr capacity for rack applications
• Constructed from stainless steel for advanced corrosion resistance
• Includes mechanical thermostat for automated temperature regulation
• Supports dual voltage operation at 460 VAC

Applications

• Outdoor industrial rack thermal management
• Indoor equipment cabinet cooling
• Environments requiring NEMA Type 4X protection
• Harsh conditions demanding corrosion-resistant enclosures

Procurement Notes

Verify the specific voltage requirement of 460 VAC against the site power supply before procurement. Confirm that the NEMA Type 4X rating aligns with the environmental exposure needs. Ensure the physical dimensions fit the designated rack space. Check compatibility with existing terminal block wiring configurations. Validate the amperage draw against circuit breaker capacities.

Selection Notes

Select this model when high corrosion resistance is critical for outdoor or harsh indoor deployments. The 4000 BTU/hr capacity suits medium-sized racks requiring active cooling. Consider the 460 VAC input constraint if standard low-voltage options are preferred. The stainless steel construction justifies use in chemically aggressive or marine-like environments where aluminum units would degrade.

Part Context

This unit belongs to the SpectraCool series, designed for robust thermal management in demanding settings. It complements Hoffman's enclosure portfolio by providing integrated climate control. The product targets sectors requiring durable, weather-proof solutions for sensitive electronic equipment housed in metal racks.
