G521246G150

Overview

The nVent Hoffman G521246G150 is a SpectraCool MCLG indoor/outdoor enclosure air conditioner designed for demanding environments. It provides 12,000 BTU/hr cooling capacity and operates on 400/460 V AC at 3.5/3.6 A, 50/60 Hz. Constructed from steel with a light gray finish, it meets NEMA 1/2/3/3R/4/12/13 and IP65/IP66 standards. The unit features an energy-efficient rotary compressor and includes a cleanable aluminum mesh filter to protect coils in dirty conditions.

Feature Summary

• Includes a cleanable, reusable aluminum mesh filter to protect coils and maintain maximum cooling performance in dirty environments.
• Utilizes an energy-efficient rotary compressor for reliable operation.
• Designed for both indoor and outdoor installation with robust environmental protection ratings.

Applications

• Cooling electrical enclosures in industrial settings
• Protecting control panels in outdoor or harsh environments
• Maintaining temperature stability in equipment cabinets requiring NEMA 4/12 or IP65/IP66 compliance

Procurement Notes

Verify the specific voltage requirement (400V vs 460V) matches your facility's power supply before ordering. Confirm that the physical dimensions of the enclosure opening accommodate the unit's mounting requirements. Ensure the ambient temperature conditions fall within the operational limits specified by nVent Hoffman for this model. Check for any required accessories such as mounting kits or additional filtration components not included in the standard package.

Selection Notes

Select this model when high cooling capacity (12,000 BTU/hr) is needed for large enclosures exposed to dust or moisture. The steel construction and multiple ingress protection ratings make it suitable for harsh industrial sites. Consider the 400/460V input compatibility if operating outside standard low-voltage regions. The inclusion of a reusable filter reduces maintenance frequency compared to filterless units in dusty areas.

Part Context

This unit belongs to the nVent Hoffman SpectraCool MCLG series, which offers indoor and outdoor climate control solutions. The G52 series typically denotes specific dimensional and capacity configurations within the product line. This particular model integrates heating capabilities in some variants, though primary documentation emphasizes its cooling function for the G521246G150 designation.

Replacement Considerations

Direct replacements must match the 12,000 BTU/hr capacity and 400/460V input specifications. Verify that substitute units meet the same NEMA and IP rating requirements for environmental protection. Physical mounting dimensions and terminal connections should be compatible with existing enclosure cutouts and wiring setups.
