Overview

The nVent DAH4001B is a 400W electric enclosure heater designed for industrial environments requiring precise temperature control. Operating on 115VAC with a nominal current of 3.72A, this fan-driven unit actively circulates warm air to prevent condensation, corrosion, and equipment failure in sensitive enclosures. Its brushed aluminum construction (7.50x4.25x4.38 inches, 2.2 lb) ensures durability and efficient heat dissipation, while the integrated thermostat maintains stable internal temperatures. Ideal for manufacturing, telecommunications, automation, and hazardous locations, the DAH4001B protects control panels, electrical cabinets, and instrumentation from extreme cold (-76°F/-60°C) and humidity. Certified for hazardous locations (Ex db IIC T4, Class I Div 1 Groups A-D), this heater meets rigorous safety standards including ATEX, IECEx, and NEC cCSAus. With a maximum operating temperature of 302°F (150°C), it delivers reliable performance in enclosures up to 302°F (150°C).
