NEMA 4 rated enclosure delivers weatherproof protection against dust and water ingress, reducing field failures and maintenance costs. This reliability translates to longer service life for control panels in harsh environments. Ideal for factory floors, outdoor equipment huts, and washdown areas. Compact 4x4x4 inch form factor supports space-constrained control panels while preserving access for servicing. Wall mounting with external feet enables quick, secure installation on uneven surfaces. This is ideal for small machine controls, instrument panels, and distributed control points in manufacturing lines. Carbon steel construction at 16 gauge delivers rigidity and durable service in industrial settings. The painted ANSI 61 gray finish adds corrosion resistance and a clean, professional appearance that matches other Eaton enclosures. Suitable for high-traffic plants and service corridors. Seamless poured-in-place gasket provides continuous seal around the door, improving moisture and dust protection. This helps maintain NEMA 4/IP-like performance even after repeated door openings and temperature cycles. Works well in washdown zones and dusty manufacturing areas. External mounting feet simplify alignment and secure mounting on walls or frames, reducing installation time. They enable robust support even on uneven backdrops and allow for easier gasket service. UL 50, CSA C22.2 and NEMA certification provide regulatory compliance and interoperability within the Eaton B-Line ecosystem. This enables straightforward procurement, reduces spec-review cycles, and supports multi-site rollouts.

FAQs
Start by locating a suitable wall stud or frame and remove the door to access the mounting area. Use the external mounting feet to align the enclosure level, then anchor it with appropriate fasteners rated for the substrate. Reinstall the door, verify gasket seating, and connect conductors through the provided knockouts or conduit fittings. This approach minimizes seal compromise and speeds up servicing.
NEMA 4 indicates a weatherproof enclosure designed to resist corrosion, water ingress, and wind-driven rain. For the 443-4LC, this translates to reliable protection for control gear in harsh factory environments, including washdown areas and exterior installations. Ensure installation follows field wiring standards to maintain the integrity of the seal and rating.
Yes. The 443-4LC is specified with external mounting feet, enabling secure wall mounting on flat or uneven surfaces. This feature simplifies alignment during installation, supports fast commissioning, and facilitates future service access without compromising gasket integrity or enclosure security.
The enclosure is carbon steel with a 16 gauge wall thickness and a painted finish in ANSI 61 gray. This combination provides rigidity, impact resistance, and a durable appearance. The material and finish are well-suited for industrial environments where corrosion resistance and long service life matter.
Ideal for small, wall-mounted control panels, process instrumentation housings, and local control points in manufacturing lines. Its corrosion-resistant finish, tight gasket, and NEMA 4 protection reduce maintenance frequency and unplanned downtime, delivering faster ROI through longer service life, easier part sourcing, and compatibility with Eaton B-Line accessories.
