Product Description

The FUNCTIONAL DEVICES mh5803l is a NEMA 1 metal enclosure housing designed for indoor electrical and control system installations. Measuring 36 inches high by 25 inches wide by 9.5 inches deep, it provides substantial interior space for mounting control boards, relays, transformers, and associated wiring. The enclosure ships with a subpanel included and features a coin latch closure for secure, tool-accessible access. It carries UL Listed approval, making it suitable for use in commercial and light industrial building automation and HVAC control panel applications. Licensed electricians and HVAC controls technicians are the primary installers.

This enclosure is suited for indoor, non-hazardous locations where a NEMA 1 rating meets the environmental requirements of the installation. Its large interior footprint makes it a practical choice for centralized control panel builds in commercial HVAC systems, building automation retrofits, and multi-component electrical assemblies. The included subpanel provides a ready-to-use mounting surface, reducing field fabrication time. The grey finish is standard for this product line.
