FAQs
FD42318-12 is designed for wall mounting with external mounting feet and a hinged cover. For proper installation, provide a level mounting surface with adequate clearance for door swing and service access, verify gasket compression by tightening mounting hardware to spec, and follow NEC and NEMA 12 guidelines. Use appropriate corrosion-resistant hardware and ensure grounding where required for your panel assembly.
The enclosure carries UL 508A and CSA C22.2 listings and a NEMA 12 rating. These certifications verify electrical safety, enclosure integrity, and protection against dust and moisture in typical industrial environments. Compliance supports safe commissioning, simplifies audits, and helps meet regulatory requirements for panel enclosures in many manufacturing and processing facilities.
Yes. The NEMA 12 rating specifies protection against dust, non-corrosive liquids, and limited ingress for typical indoor and some outdoor applications. Combined with a seamless poured-in-place gasket and a painted ANSI 61 gray carbon steel body, the FD42318-12 reduces ingress and simplifies maintenance in challenging environments.
The enclosure measures 42 inches in height, 31 inches in width, and 18 inches in depth, with a 14-gauge wall and 14-gauge metal thickness. These dimensions influence the footprint, internal layout for controllers and terminal blocks, and clearances for door operation and service access. Plan for mounting, wiring space, and future expansion when integrating into a larger control system.
The hinged, easily accessible cover, removable panels, and gasket integrity minimize maintenance downtime and inspection effort. The robust carbon steel construction resists impact and corrosion in typical industrial settings, reducing replacement costs and service interruptions. Over time, this translates to lower total cost of ownership and improved panel reliability for high-uptime applications.
