G521246G102

Overview

The Hoffman G521246G102 is a SpectraCool series enclosure air conditioner designed for indoor and outdoor use. It provides a nominal cooling capacity of 12,000 BTU/hr. The unit operates on a 3-phase power supply with a voltage range of 400 to 460 VAC at 50/60 Hz. Maximum current draw is 3.5 A. Constructed from stainless steel with a brushed #4 finish, it meets NEMA 4X standards. Dimensions are 52.69 x 17.12 x 11.66 inches. Maximum ambient temperature is 131°F.

Feature Summary

• Sealed compressor-based cooling system for reliable thermal management
• Stainless steel construction with advanced corrosion protection level 1
• NEMA 4X rated enclosure suitable for harsh indoor and outdoor environments

Applications

• Industrial control enclosures requiring high-capacity cooling
• Outdoor electrical cabinets in corrosive environments
• Large machinery housing needing 3-phase power integration

Procurement Notes

Verify the specific voltage configuration (400-460 VAC) and phase requirements (3-phase) against site infrastructure before procurement. Confirm that the physical dimensions (52.69 x 17.12 x 11.66 inches) fit the target enclosure opening. Ensure the mounting method (side mount) aligns with the installation design. Check for any specific certification requirements relevant to the deployment region.

Selection Notes

Select this model when high cooling capacity (12,000 BTU) is required for large enclosures. The 3-phase power requirement limits suitability to facilities with industrial power distribution. The stainless steel construction and NEMA 4X rating make it appropriate for wet or corrosive locations where standard aluminum units would fail. Consider the weight (152 lb) for structural support needs.

Part Context

This unit belongs to the Hoffman SpectraCool series, which offers sealed enclosure cooling solutions. The G521246G102 variant specifically targets applications demanding robust corrosion resistance and high thermal output. It is part of a broader lineup offering various capacities and power configurations to suit different enclosure sizes and environmental conditions.

Replacement Considerations

Direct replacements must match the 12,000 BTU capacity, 3-phase 460V input, and NEMA 4X rating. Verify dimensional compatibility for existing cutouts. Units with lower corrosion protection levels may not be suitable for the same environment. Ensure the replacement supports side-mount installation if space constraints apply.
