Eaton Specification Sheet - EIH20 MF
Copper-free aluminum construction reduces weight and corrosion risk while maintaining rugged durability for field use. The EIH20 MF’s 3/4" trade size and 2" cover opening streamline wiring, testing, and maintenance, enabling faster installations and lower labor costs on active plant floors. This enclosure’s NEC/CEC compliance and hazardous location ratings ensure safe, compliant installations in oil and gas, chemical processing, and other high-risk environments, minimizing regulatory risk and rework. NEMA ratings of 3, 4, 4X, 7, and 9 extend protection against dust, water, and corrosion, supporting reliable outdoor operation and harsh-industrial performance. Cast mounting feet provide stable mounting and vibration resistance for wall- or cabinet-mounted instruments, reducing mounting time and field adjustments. Compatibility with standard control panels and field wiring simplifies upgrades to sensors, meters, and controllers, while installation instructions and UL certifications help accelerate project timelines and improve total cost of ownership. Real-world benefits include reduced maintenance intervals, lower spare-part inventories, and enhanced safety by keeping hazardous instrumentation protected in demanding environments.
