Description

Square D® NF Merchandised Panelboards MH44, is a enclosure steel panelboard box has NEMA1 degree of protection, cULus certified. Warranty period is 18 month. .

Features

  • Precision-engineered as a standard MH-type enclosure, this box is designed exclusively for 400A and 600A Square D NQ and NF panelboards. Utilizing the exact OEM enclosure prevents costly field modifications and ensures a seamless, professional fit for your interior, saving hours of labor during commercial electrical fit-outs.
  • The 44"H x 20"W x 5.75"D dimensions provide an optimized internal volume that easily accommodates heavy-gauge copper or aluminum conductors. This spacious design prevents wire crowding and insulation damage, ensuring your industrial installation meets NEC wire-bending space requirements and maintains proper airflow for heat dissipation.
  • Rated for NEMA Type 1 indoor protection, this heavy-duty steel housing shields your sensitive circuit breakers and busbars from dust, light, and accidental contact. It is the industry-standard choice for electrical rooms, data centers, and commercial basements where a robust, secure barrier is required to protect the building's core power distribution system.
  • Fabricated from high-grade, galvanized steel with a phosphate-treated finish, this box is built to resist corrosion and physical impact during and after installation. The pre-punched knockouts and sturdy mounting holes allow for rapid, secure anchoring to masonry or stud walls, ensuring your electrical infrastructure remains stable and code-compliant for decades.
