Durable NEMA Steel Electrical Enclosure – IP66 Rated for Harsh Environments
This rugged electrical enclosure is constructed from 1.5 mm cold-rolled carbon steel, precision cut and welded for superior strength and durability. Certified with CE and ROHS, it offers excellent wear resistance, making it ideal for both indoor and outdoor applications in demanding environments like factories, construction sites, malls, and residential areas.
Engineered with an IP66 waterproof rating, the enclosure features a high-quality foam sealing strip that prevents dirt, dust, and water ingress—even when the lid is open. The reinforced hinged door is designed to withstand pressure without damage, while the premium lock core enhances safety and prevents unauthorized access.
For ease of use, the box includes a detachable galvanized mounting backplate for quick installation of electrical components, along with four pre-drilled mounting holes for secure wall attachment. Thoughtful design touches—like smooth cutouts, pre-installed grounding screws, and a threading-friendly bottom—ensure both safety and convenience, making this enclosure a reliable solution for your electrical protection needs.
