Overview

The nVent DAH2002A electric enclosure heater (SKU: DAH2002A) is a 200W, 230VAC thermostatically controlled unit designed to protect critical electrical and electronic equipment from low temperatures, condensation, and corrosion. Engineered for industrial enclosures, this heater maintains stable internal temperatures to prevent equipment failure in harsh environments. Key specifications include a compact 5.50x4.00x4.00 inch brushed aluminum housing, 230VAC operation at 50/60Hz with 0.9A current draw, and a power output of 200W. The thermostatically controlled, fan-driven design ensures even heat distribution by drawing cool air from the enclosure bottom, passing it over the heating element and thermostat, then expelling heated air from the top. This creates a consistent thermal environment that prevents condensation formation and mitigates corrosion risks. Ideal for manufacturing, automation, telecommunications, and outdoor electrical cabinets, the DAH2002A safeguards control panels, VFDs, and sensitive instrumentation. Its durable construction and easy installation make it a reliable thermal management solution for protecting valuable assets in demanding industrial applications.
